Narated By 'Abdullah bin 'Amr : The Prophet said, "Convey (my teachings) to the people even if it were a single sentence, and tell others the stories of Bani Israel (which have been taught to you), for it is not sinful to do so. And whoever tells a lie on me intentionally, will surely take his place in the (Hell) Fire."
