Arabic text
عن أبي هريرة رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم: «أَكْمَلُ الْمُؤْمِنِينَ إِيمَانًا أَحْسَنُهُمْ خُلُقًا، وَخَيْرُكُمْ خَيْرُكُمْ لِنِسَائِهِمْ».
Translation
Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah’s peace and blessings be upon him) said: "The most perfect believer in terms of his faith is the one who has the most excellent manners, and the best of you are those who are best to their womenfolk."
Explanation
The Prophet (may Allah's peace and blessings be upon him) informs that the most perfect people in terms of their faith are those who possess excellent manners, have cheerful faces, do good, speak kind words, and refrain from hurting others. And that the best believers are those who are kindest to their womenfolk - their wives, daughters, sisters, and other female relatives - for they are among the worthiest of good treatment.
