Sayyiduna Jabir (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "O Banu Abd al-Muttalib! Feeding others will make you enter Paradise (or: will secure you a place in Paradise), so feed others and speak good words." The chain of this narration contains a narrator, Abdullah bin Muhammad al-Abbadi, and I do not know him. The rest of the narrators of this narration are the narrators of the Sahih.
