.يَـٰٓأَيُّهَا ٱلنَّاسُ إِنَّا خَلَقۡنَٰكُم مِّن ذَكَرٖ وَأُنثَىٰ وَجَعَلۡنَٰكُمۡ شُعُوبٗا وَقَبَآئِلَ لِتَعَارَفُوٓاْۚ إِنَّ أَكۡرَمَكُمۡ عِندَ ٱللَّهِ أَتۡقَىٰكُمۡۚ إِنَّ ٱللَّهَ عَلِيمٌ خَبِيرٞ
13. O mankind! We have created you from a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honourable of you with Allâh is that (believer) who has At-Taqwâ [i.e. he is one of the Muttaqûn (the pious. See V.2:2)]. Verily, Allâh is All-Knowing, All-Aware.
The Messenger of Allah said: "When someone whose religion and character you are pleased with proposes to (someone under the care) of one of you, then marry to him. If you do not do so, then there will be turmoil (Fitnah) in the land and abounding discord (Fasad)."
