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

Messenger of Allah (ﷺ) said, "The believers who show the most perfect Faith are those who have the best behaviour, and the best of you are those who are the best to their wives". <b>[At-Tirmidhi, who categorized it as Hadith Hasan Sahih]</b>.

وعن أبي هريرة رضي الله عنه قال ‏:‏ قال رسول الله صلى الله عليه وسلم ‏

‏أكمل المؤمنين إيمانا أحسنهم خُلقا، وخياركم خياركم لنسائهم‏

<b>Guidance from the Hadith:</b><br> 1) Faith is of various degrees, as indicated in the verse where Allah Almighty says: {...and the believers may increase in faith} The more excellent one’s character is, the more it is indicative of the strength of his faith.<br> 2) The best among people are those who are best in treating their families.<br> 3) Relatives are the most deserving of favor. So, if one is to do good to others, then his family is the worthiest of receiving such good.<br> <br> <b>Benefit:</b><br> One should be well-mannered with Allah Almighty and with His slaves. To be well-mannered with Allah Almighty is realized by accepting His Shariah, fully and willingly submitting to it with reassurance, and to be pleased with the predestination of Allah Almighty. Being well-mannered with people is to refrain from harming them, but treat them with generosity and show patience in the face of harm received from them.
