Holy Qur’an 30:21
ن أَنفُسِكُم أَزواجًا لِتَسكُنوا إِلَيها وَجَعَلَ بَينَكُم مَوَدَّةً وَرَحمَةً إِنَّ في ذلِكَ لَآياتٍ لِقَومٍ يَتَفَكَّرونَ
Among His proofs is that He created for you spouses from among yourselves, in order to have tranquility and contentment with each other, and He placed in your hearts love and care towards your spouses. In this, there are sufficient proofs for people who think.
Tirmidhi, Sahih Hadith
The most perfect believer in the matter of faith is one who has excellent behavior; and the best among you are those who behave best towards their wives.
