So travel through the earth and see what was the end of those who rejected the messengers. (Al Quran 16: 37)
The Treasury at Petra
Where did the ThamudNabataean who built Petra come from? According to the Holy Quran they were descendents of the ‘Ad and migrated north from southern Arabia. (Al Quran 7:73-74) According to Glen W Bowersock:
The people that we know as the Nabataean Arabs held a place on the historical stage for some eight hundred years. During this time they lived uninterruptedly alongside Jews, Greeks, Romans, and other Arabs, both nomadic and sedentary, throughout the long pre-Islamic centuries after Alexander the Great. Between the conquests of Alexander and Muhammad they occupied the territory of Transjordan (the modern Hashemite Kingdom of Jordan) as well as the northwest corner of the Arabian Peninsula, southern Syria, and the Negev. For approximately the first half of the eight hundred years in which they can be tracked, the Nabataeans had an autonomous kingdom of their own, and for the second half they lived within provinces of the Roman Empire, notably the province of Arabia and a later configuration of two provinces called Third Palestine and Arabia. They were present, although in modest numbers, in Greek cities of the Decapolis at the margins of their homeland. The territorial extent of Nabataean culture across this long period remained essentially the same, bringing the people into close contact with their neighbors in Palestine and Syria. In the third century AD the deified Nabataean king Obodas was still worshipped at Avdat in the Negev, and in documents from the fourth century AD the northern Nabataean city of Bostra can still be described as a city of Syria. 
The Quranic term Al Hijr may be applicable to Petra rather than Madain Salih. We havea few clues in the Holy Quran to identify the people of Al Hijr.
1. They hew houses in mountains.
2. Their ruins do no lie on a frequented highway (Caravan route).
3. The earthquake that destroyed themstruck in the morning.
4. Their houses and inhabitation gave them a relative security.
Some of these clues are stated and some are implied from the context of the following verses of the Holy Quran:
The People of Hijr also rejected the Messengers as liars. We gave them Our Signs too, but they turned away from them. They used to hew out houses in the mountains, dwelling therein in security. The chastisement seized them in the morning; and all that they had worked at availed them nothing. (AlQuran 15:81-85)
Whereas some of these clues are applicable to Madain Salih but all of these are applicable to Petra. Madain Salih lies on a known Caravan route and that was the reason why it is recorded in history that the Holy Prophet Muhammad, may peace be on him, had passed by Madain Salih.  There is a narrow passage (Siq) that leads to Petra, that is shown in a picture below.
The Arabic wordحجر’Hijr’ not only means a stone but also an enclosure, a chamber, an apartment or a tomb; possibly a fortress. 
Enclosed by towering rocks and watered by a perennial stream, Petra possessed the advantages of a fortress, offering the inhabitants a dwelling of security. Al Hijr was indeed a befitting title for Petra. Madain Saleh, that is in north of Madinah and has about 130 dwellings and tombs that extend over some 13 kilometers, cannot be considered to be an enclosure ora fortress, if we translate ‘Al Hijr’ as such. 
From Wikipedia, the free encyclopedia
( Greek“πέτρα” (petra), meaning
rock; Arabic: البتراء,Al-Batrāʾ) is a historic and archaeological city in the Jordanian governorate of Ma’an that has rock cut architecture and water conduits system. Established sometime around the 6th century BC as the capital city of the Nabataeans ,  it is a symbol of Jordan as well as its most visited tourism attraction.  It lies on the slope of Mount Hor in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba . Petra was chosen as one of the New Seven Wonders of the World in 2007 and a World Heritage Site since 1985. Petra was chosen by the BBC as one of “the 40 places you have to see before you die”. 
The site remained unknown to the Western world until 1812, when it was introduced by Swiss explorer Johann Ludwig Burckhardt . It was described as “a rose-red city half as old as time” in a Newdigate Prize -winning sonnet by John William Burgon . UNESCO has described it as “one of the most precious cultural properties of man’s cultural heritage.” 
Pliny the Elder and other writers identify Petra as the capital of the Nabataeans, Aramaic -speaking Semites , and the centre of their caravan trade. Enclosed by towering rocks and watered by a perennial stream , Petra not only possessed the advantages of a fortress, but controlled the main commercial routes which passed through it to Gaza in the west, to Bosra and Damascus in the north, to Aqaba and Leuce Come on the Red Sea , and across the desert to the Persian Gulf .
The end of the Siq, the narrow passage of Petra, with its dramatic view of Al Khazneh (The Treasury)
Excavations have demonstrated that it was the ability of the Nabataeans to control the water supply that led to the rise of the desert city, creating an artificial oasis . The area is visited by flash floods and archaeological evidence demonstrates the Nabataeans controlled these floods by the use of dams , cisterns and water conduits. These innovations stored water for prolonged periods of drought , and enabled the city to prosper from
The narrow passage (Siq) that leads to Petra
Although in ancient times Petra might have been approached from the south via Saudi Arabiaon a track leading around Jabal Haroun (“Aaron’s Mountain”), across the plain of Petra, or possibly from the high plateau to the north, most modern visitors approach the site from the east. The impressive eastern entrance leads steeply down through a dark, narrow gorge (in places only 3–4m (9.8–13ft) wide) called the
Siq(“the shaft”), a natural geological feature formed from a deep split in the sandstone rocks and serving as a waterway flowing into Wadi Musa . At the end of the narrow gorge stands Petra’s most elaborate ruin, Al Khazneh(popularly known as “the Treasury”), hewn into the sandstone cliff.
El Deir (“The Monastery”)
A little further from the Treasury, at the foot of the mountain called
en-Nejr, is a massive theatre, so placed as to bring the greatest number of tombs within view. At the point where the valley opens out into the plain, the site of the city is revealed with striking effect. The amphitheatre has been cut into the hillside and into several of the tombs during its construction. Rectangular gaps in the seating are still visible. Almost enclosing it on three sides are rose-colored mountain walls, divided into groups by deep fissures, and lined with knobs cut from the rock in the form of towers.
Evidence suggests that settlements had begun in and around Petra in the eighteenth dynasty of Egypt (1550-1292 BCE). It is listed in Egyptian campaign accounts and the Amarna letters as Pel, Sela or Seir. Though the city was founded relatively late, a sanctuary existed there since very ancient times. Stations 19 through 26 of the stations list of Exodus are places associated with Petra.  This part of the country was Biblically assigned to the Horites , the predecessors of the Edomites .  The habits of the original natives may have influenced the Nabataean custom of burying the dead and offering worship in half-excavated caves. Although Petra is usually identified with Selawhich means a
rock,the Biblical references  refer to it as “the cleft in the rock”, referring to its entrance. 2 Kingsxiv. 7 seems to be more specific. In the parallel passage, however, Sela is understood to mean simply “the rock” (2 Chr. xxv. 12, see LXX).
On the authority of Josephus(
Antiquities of the Jewsiv. 7, 1~ 4, 7) Eusebius and Jerome(Onom. sacr.286, 71. 145, 9; 228, 55. 287, 94) assert thatRekemwas the native name andRekemappears in the Dead Sea scrolls as a prominent Edom site most closely describing Petra and associated with Mount Seir . But in the Aramaic versions Rekem is the name of Kadesh , implying that Josephus may have confused the two places. [ citation needed ] Sometimes the Aramaic versions give the formRekem-Geyawhich recalls the name of the village El-ji, southeast of Petra. The capital, however, would hardly be defined by the name of a neighboring village. [ citation needed ] The Semitic name of the city, if not Sela, remains unknown. The passage in Diodorus Siculus (xix. 94–97) which describes the expeditions which Antigonussent against the Nabataeans in 312 BCE is understood to throw some light upon the history of Petra, but the “petra” referred to as a natural fortress and place of refuge cannot be a proper name and the description implies that the town was not yet in existence.
The only place in Petra where the name “Rekem” occurs was in the rock wall of the Wadi Musa opposite the entrance to the Siq. About twenty years ago the Jordanians built a bridge over the wadi and this inscription was buried beneath tons of concrete. 
More satisfactory evidence of the date of the earliest Nabataean settlement may be obtained from an examination of the tombs. Two types may be distinguished: the Nabataean and the Greco-Roman . The Nabataean type starts from the simple pylon-tomb with a door set in a tower crowned by a parapet ornament, in imitation of the front of a dwelling-house. Then, after passing through various stages, the full Nabataean type is reached, retaining all the native features and at the same time exhibiting characteristics which are partly Egyptian and partly Greek . Of this type there exist close parallels in the tomb-towers at el-I~ejr in north Arabia, which bear long Nabataean inscriptions and supply a date for the corresponding monuments at Petra. Then comes a series of tombfronts which terminate in a semicircular arch, a feature derived from north Syria . Finally come the elaborate façades copied from the front of a Roman temple ; however, all traces of native style have vanished. The exact dates of the stages in this development cannot be fixed. Strangely, few inscriptions of any length have been found at Petra, perhaps because they have perished with the stucco or cement which was used upon many of the buildings. The simple pylon-tombs which belong to the pre-Hellenic age serve as evidence for the earliest period. It is not known how far back in this stage the Nabataean settlement goes, but it does not go back farther than the 6th century BCE.
A period follows in which the dominant civilization combines Greek, Egyptian and Syrian elements, clearly pointing to the age of the Ptolemies . Towards the close of the 2nd century BCE, when the Ptolemaic and Seleucid kingdoms were equally depressed, the Nabataean kingdom came to the front. Under Aretas III Philhellene , (c.85–60 BCE), the royal coins begin. The theatre was probably excavated at that time, and Petra must have assumed the aspect of a Hellenistic city. In the reign of Aretas IV Philopatris , (9 BCE–40 CE), the fine tombs of the el-I~ejr [?] type may be dated, and perhaps also the great High-place.
In 106 CE, when Cornelius Palma was governor of Syria, that part of Arabia under the rule of Petra was absorbed into the Roman Empire as part of Arabia Petraea , becoming capital. The native dynasty came to an end. But the city continued to flourish. A century later, in the time of Alexander Severus , when the city was at the height of its splendor, the issue of coinage comes to an end. There is no more building of sumptuous tombs, owing apparently to some sudden catastrophe, such as an invasion by the neo- Persian power under the Sassanid Empire . Meanwhile, as Palmyra (fl. 130–270) grew in importance and attracted the Arabian trade away from Petra, the latter declined. It seems, however, to have lingered on as a religious centre. A Roman road was constructed at the site. Epiphanius of Salamis (c.315–403) writes that in his time a feast was held there on December 25 in honor of the virgin Khaabou (Chaabou) and her offspring Dushara(
A close up of the Theater.
The Nabataeans worshipped the Arabgods and goddesses of the pre-Islamic times as well as few of their deified kings. One, Obodas I , was deified after his death. Dushara was the main male god accompanied by his female trinity: Al-‘Uzzá , Allat and Manāt . Many statues carved in the rock depict these gods and goddesses.
The Monastery, Petra’s largest monument, dates from the 1st century BCE. It was dedicated to Obodas I and is believed to be the symposium of Obodas the god. This information is inscribed on the ruins of the Monastery (the name is the translation of the Arabic “Ad-Deir”).
Christianity found its way to Petra in the 4th century CE, nearly 500 years after the establishment of Petra as a trade center. Athanasius mentions a bishop of Petra (Anhioch. 10) named Asterius . At least one of the tombs (the “tomb with the urn”?) was used as a church. An inscription in red paint records its consecration “in the time of the most holy bishop Jason” (447). After the Islamic conquest of 629–632 Christianity in Petra, as of most of Arabia, gave way to Islam. During the First Crusade Petra was occupied by Baldwin I of the Kingdom of Jerusalem and formed the second fief of the barony of Al Karak (in the lordship of Oultrejordain) with the title
According to Arab tradition, Petra is the spot where Moses struck a rock with his staff and water came forth, and where Moses’ brother, Aaron , is buried , at Mount Hor , known today as Jabal Haroun or Mount Aaron. The Wadi Musa or “Wadi of Moses” is the Arab name for the narrow valley at the head of which Petra is sited. A mountaintop shrine of Moses’ sister Miriam was still shown to pilgrims at the time of Jerome in the 4th century, but its location has not been identified since. 
Petra declined rapidly under Roman rule, in large part due to the revision of sea-based trade routes. In 363 an earthquake destroyed many buildings, and crippled the vital water management system.  The ruins of Petra were an object of curiosity in the Middle Ages and were visited by SultanBaibars of Egypt towards the end of the 13th century. The first European to describe them was Johann Ludwig Burckhardt in 1812.
Because the structures weakened with age, many of the tombs became vulnerable to thieves, and many treasures were stolen.
Threats to Petra
The site suffers from a host of threats, including collapse of ancient structures, erosion due to flooding and improper rainwater drainage, weathering from salt upwelling, improper restoration of ancient structures, and unsustainable tourism.  The latter has increased substantially ever since the site was named one of the New Seven Wonders of the World in 2007. 
On December 6, 1985, Petra was designated a World Heritage Site .
In 2006 the design of a Visitor Centre began.
In popular culture
Petra was the main topic in John William Burgon‘s Poem
|“||It seems no work of Man’s creative hand,by labour wrought as wavering fancy planned;But from the rock as if by magic grown,eternal, silent, beautiful, alone!Not virgin-white like that old Doric shrine,where erst Athena held her rites divine;Not saintly-grey, like many a minster fane,that crowns the hill and consecrates the plain;But rose-red as if the blush of dawn,that first beheld them were not yet withdrawn;The hues of youth upon a brow of woe,which Man deemed old two thousand years ago,match me such marvel save in Eastern clime,a rose-red city half as old as time.||”|
