Q.S. Ar-Rum [30]: 21
وَمِنْ اٰيٰتِهٖٓ اَنْ خَلَقَ لَكُمْ مِّنْ اَنْفُسِكُمْ اَزْوَاجًا لِّتَسْكُنُوْٓا اِلَيْهَا وَجَعَلَ بَيْنَكُمْ مَّوَدَّةً وَّرَحْمَةًۗ اِنَّ فِيْ ذٰلِكَ لَاٰيٰتٍ لِّقَوْمٍ يَّتَفَكَّرُوْنَ
"And among His signs is that He created for you spouses from among yourselves so that you may find tranquility in them; and He placed between you affection and mercy. Indeed, in that are signs for a people who reflect."
