It is narrated from him (narrator of the Hadith above) from Muhammad ibn Ali from Muhammad ibn Furat from abu Ja’far (a.s.) who has said the following: “The Messenger of Allah has said in one of his speeches, ‘Beware of causing suffering and disappointment to parents. The fragrance of paradise can be sensed from a distance of a one thousand year journey, but those causing suffering and disappointments to parents, those failing to maintain good relations with relatives, an old fornicating man and one who drags his garments out of arrogance and boastfulness will not sense such fragrance. Greatness belongs only to Allah, Lord of the worlds.’”
