It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that Sayyiduna Abu Talhah (may Allah be pleased with him) sent me to the Messenger of Allah (peace and blessings be upon him) with harirah (a thin dish of flour cooked in milk or ghee), which he had prepared especially for him (peace and blessings be upon him), and said: "Go and invite the Messenger of Allah (peace and blessings be upon him) to me (for a meal)." Sayyiduna Anas (may Allah be pleased with him) says: I went to him (peace and blessings be upon him). When the Messenger of Allah (peace and blessings be upon him) saw me, while he (peace and blessings be upon him) was sitting among his Companions, he (peace and blessings be upon him) fixed his gaze on me until all the people also began to look at me, and I felt embarrassed. Then he (peace and blessings be upon him) asked: "Has Abu Talhah sent for us?" I said: "Yes." So the Messenger of Allah (peace and blessings be upon him) said: "Stand up."
Sayyiduna Anas (may Allah be pleased with him) says: All the people stood up with him (peace and blessings be upon him), and I ran to Sayyiduna Abu Talhah (may Allah be pleased with him) and informed him of the situation. So he came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, I only prepared a little food for your sake, which will not be enough for all of them." He (peace and blessings be upon him) said: "It will suffice for all of them, in sha' Allah (if Allah wills)."
Then the Messenger of Allah (peace and blessings be upon him) went inside and supplicated for blessing, and then said: "Allow ten men to come in." They came in and ate until they were full, and then went out. Then he (peace and blessings be upon him) said: "Allow another ten." So another ten came in, and they all ate their fill as well. Then he (peace and blessings be upon him) took the leftover food, gathered it together, and supplicated for blessing in it, and it returned to its original state. Then he (peace and blessings be upon him) said: "Take this."
No one narrated this hadith from Sa'd bin Sa'id except Yahya bin Sa'id al-Umawi.
