Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates from his mother, Sayyidah Umm Sulaym (may Allah be pleased with her); she said: I had a sheep, and I collected a skin of its ghee, then sent it with Zaynab and said: "O Zaynab! Deliver this skin to the Messenger of Allah (peace and blessings be upon him) so that he may use it as a condiment." The narrator said: So Zaynab came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah! This is ghee that Umm Sulaym has sent to you." He (peace and blessings be upon him) said: "Empty her skin for her." So the skin was emptied and given back to her. She came back, and Umm Sulaym was not at home, so I hung the skin on a peg. Then Umm Sulaym came and saw that the skin was full and ghee was dripping from it, and she said: "O Zaynab! Did I not order you to deliver this skin to the Messenger of Allah (peace and blessings be upon him) so that he could use it as a condiment?" Zaynab said: "I did so; if you do not believe me, come with me to the Messenger of Allah (peace and blessings be upon him)." So Umm Sulaym (may Allah be pleased with her) and Zaynab both went to the Messenger of Allah (peace and blessings be upon him), and she said: "I sent a skin of ghee to you with her." He (peace and blessings be upon him) said: "She has brought it." I said: "By the One who sent you with guidance and the religion of truth, it is full of ghee and dripping!" The Prophet (peace and blessings be upon him) said: "O Umm Sulaym! Are you surprised that Allah has fed you?"
