Hazrat Ja'far bin Muhammad narrates from his esteemed father, who says that we presented ourselves before Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both), and we asked him about the Hajj of the Prophet Muhammad (peace and blessings be upon him). He said that the Prophet stayed at Muzdalifah and said: "I have stayed at this place, and all of Muzdalifah is a place for staying."
