Sura al-Rūm 30:21

وَمِنْ ءَايَٰتِهِۦٓ أَنْ خَلَقَ لَكُم مِّنْ أَنفُسِكُمْ أَزْوَٰجًا لِّتَسْكُنُوٓا۟ إِلَيْهَا وَجَعَلَ بَيْنَكُم مَّوَدَّةً وَرَحْمَةً إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍ لِّقَوْمٍ يَتَفَكَّرُونَ

wa-min āyātihi an khalaqa la-kum min anfusikum azwājan llitaskunū ilayhā wa-jaʿala baynakum mawaddatan wa-raḥmatan inna fī dhālika la-āyātin li-qawmin yatafakkarūna

And among His Signs is this, that He created for you mates from among yourselves, that ye may dwell in tranquillity with them, and He has put love and mercy between your (hearts): verily in that are Signs for those who reflect.
