(Enjoin ye righteousness upon mankind while ye yourselves forget (to practise it)?) [2:44]. Said Ibn �Abbas, according to the narration of al-Kalbi>Abu Salih through the aforementioned chain of transmission: �This was revealed about the Jews of Medina. One of them would say to his brother-in-law, relatives or Muslims with whom they had milk relations: �Hold firm to your religion and that with which this man � meaning Muhammad, Allah bless him and give him peace � commands you, for what he has brought is the truth�. They used to enjoin people to follow Islam while abstaining themselves from doing so�.
