Hadith: Let not a believing man hate a believing woman. If he dislikes one of her characteristics, he will be pleased with another

عَنْ أَبِي هُرَيْرَةَ رضي لله عنه قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:

«لَا يَفْرَكْ مُؤْمِنٌ مُؤْمِنَةً، إِنْ كَرِهَ مِنْهَا خُلُقًا رَضِيَ مِنْهَا آخَرَ» أَوْ قَالَ: «غَيْرَهُ».
[صحيح] - [رواه مسلم]

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Let not a believing man hate a believing woman. If he dislikes one of her characteristics, he will be pleased with another."
Sahih/Authentic. - [Muslim]

Explanation

This Hadīth means that a man should not hate or be hostile towards his wife for disliking any of her characteristics, since he will surely find other characteristics to like. One needs to be fair and thus deal with others appropriately. Fairness entails that one weighs good and bad things, focuses on whichever more frequent and more effective, and behaves accordingly.
