A hadith like this is narrated by Ibn Numair with a slight variation of words.
The Prophet Muhammad ﷺ taught his followers that having good manners was an important part of being a Muslim because it shows that we have strong faith in God’s teachings and that we strive to live according to His will. He said “the most perfect believer in respect of faith is he who is best of them in manners” meaning that those who have strong faith should also strive for excellence when it comes to their behavior towards others.
This hadith reminds us all about the importance of having good character traits such as kindness, patience, humility, honesty etc., which are essential components for living an Islamic life according to God’s will. We should always strive towards perfection when it comes our character traits so that we may become closer to God through our actions rather than just words alone.
