In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
I was sent to perfect noble manners.
This hadeeth is from the Jawaami Al kalim of the Messenger [i.e. a precise statement whose meaning is vast]. In it [i.e. this hadeeth] is proof regarding the importance of good manners; and how can that not be the case when it is the case that the Prophet [sallal laahu alayhi wasallam] said [in another hadeeth], “Righteousness is good character”. Therefore, it is obligated on a believer to have good manners in his relationship with his Lord and in his dealings with the people. His manners should be based on the judgement of the noble Islamic legislation – in speech, deeds, dealings and all his actions. [At-taleeqaatul Maleehah Alaa Silsilah Al-Ahaadeeth As-Saheehah. Vol 1.
