Ar-Rum 30:21

Wamin ayatihi an khalaqa lakummin anfusikum azwajan litaskunoo ilayha wajaAAalabaynakum mawaddatan warahmatan inna fee thalika laayatinliqawmin yatafakkaroon

And of His signs is that He created for you from yourselves mates that you may find tranquility in them; and He placed between you affection and mercy. Indeed in that are signs for a people who give thought.

And it is among His signs that He has created for you wives from among yourselves, so that you may find tranquility in them, and He has created love and kindness between you. Surely in this there are signs for a people who reflect.
