O mankind, We have created you from a male and a female and have made you into nations and tribes for you to know one another. Truly, the noblest of you with God is the most pious.* Truly, God is All-Knowing, All-Aware.
Quran, 49:13
*:A pious person is a believer who abstains from all kinds of sins, performs all good deeds that God commands us to do, and fears and loves God.
