Mishkat al-Masabih 13 Marriage كتاب النكاح 181

قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَكْمَلُ الْمُؤْمِنِينَ إِيمَانًا أَحْسَنُهُمْ خُلُقًا وَخِيَارُكُمْ خِيَارُكُمْ لِنِسَائِهِمْ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَرَوَاهُ أَبُو دَاوُد إِلَى قَوْله «خلقا»

Abu Huraira reported God’s Messenger as saying, “The believers who show the most perfect faith are those who have the best disposition and the best of you are those who are best to their wives.” Tirmidhi transmitted it, saying this is a hasan sahih tradition, and Abu Dawud transmitted it up to “disposition.”
