Foundation of my dream!
Martin Luther King all his life was trying to perfect the understanding of ‘We hold these truths to be self-evident, that all men are created equal,’ for USA. It is reasonable to assume that if he had seen the global village, as it exists today with social media and global discussion forums, he would have wanted to further perfect the vision of ‘We hold these truths to be self-evident, that all men and women are created equal,’ and extend this to every citizen of our planet earth!

If Martin Luther King had such a dream, it could be well founded on the following verses of the Holy Quran:

O ye people! fear your Lord, Who created you from a single soul and created therefrom its mate, and from them twain spread many men and women; and fear Allah, in Whose name you appeal to one another, and fear Him particularly respecting ties of relationship. Verily, Allah watches over you. (Al Quran 4:2)

And:

O mankind, We have created you from a male and a female; and We have made you into tribes and sub-tribes that you may recognize one another. Verily, the most honorable among you, in the sight of Allah, is he who is the most righteous among you. Surely, Allah is All-knowing, All-Aware. (Al Quran 49:14)

Incidentally, there are verses in the Holy Quran predicting our global village and ease of communication in it in Sura Takwir.
