In one famous Hadith, the Prophet Muhammad (PBUH) is reported to have said, “All of humanity are as equal as the teeth of a comb.”  It is recorded that once, while the Prophet Muhammad (PBUH) sat with his companions, a funeral cortege passed by and he stood up out of respect. A companion remarked that this was only the funeral of a Jew, implying that that was far too unimportant for the Prophet’s attention. He challenged this by asking, “Was he then not also a human being?” 

In the view of Allah (God) the whole of humanity consists of one single community.
