It is narrated from the husband of Abu Jahl's daughter, who narrates from Abu Jahl's daughter; she said: The Messenger of Allah (peace and blessings be upon him) passed by us and asked for water, so I got up with a jug to give him (peace and blessings be upon him) to drink. Meanwhile a man wearing two green garments asked him (peace and blessings be upon him) a question, and he (peace and blessings be upon him) said: "That you worship Allah, associating nothing with Him, establish the prayer, and pay the zakah." Then he said: "The best of my Ummah is my generation, then those who come after them."
Imam al-Tabarani (may Allah have mercy on him) said: Shu'bah made an error in the chain of this hadith. (Note: This report relates to the daughter of Abu Jahl rather than Durrah bint Abi Lahab, who is named in the heading of the chapter.)
