يٰأَيُّهَا ٱلنَّاسُ إِنَّا خَلَقْنَاكُم مِّن ذَكَرٍ وَأُنْثَىٰ وَجَعَلْنَاكُمْ شُعُوباً وَقَبَآئِلَ لِتَعَارَفُوۤاْ إِنَّ أَكْرَمَكُمْ عِندَ ٱللَّهِ أَتْقَاكُمْ إِنَّ ٱللَّهَ عَلِيمٌ خَبِيرٌ

Quran says:

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.2 Truly, God is All-Knowing,All-Aware.  (Qur’an, 49:13)
