It is reported from Abu Hurairah (May Allah be pleased with him):

He said: The messenger of Allah ﷺ said:

The most perfect of believers in faith, are those who are best in character, and the best of you, are those who are best to their women.

(Narrated by Tirmidhi)

عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ “‏ أَكْمَلُ الْمُؤْمِنِينَ إِيمَانًا أَحْسَنُهُمْ خُلُقًا وَخِيَارُكُمْ خِيَارُكُمْ لِنِسَائِهِمْ خُلُقًا [الترمذي]
