Malik bin Hamzah bin Abi Usayd al-Sa'idi (may Allah have mercy on him) narrates from his father, from his grandfather Abu Usayd al-Sa'idi (may Allah be pleased with him), who said: The Messenger of Allah (peace and blessings be upon him) said to al-Abbas bin Abd al-Muttalib: "O Abu al-Fadl! Do not leave your house tomorrow, you and your sons, until I come to you." So they waited for him (peace and blessings be upon him) until he came after the forenoon. He went in to them and said: "As-salamu alaykum." He said: Wa alaykas-salam wa rahmatullahi wa barakatuh. He (peace and blessings be upon him) said: "How did you begin your morning?" He said: In good health, praise be to Allah. He (peace and blessings be upon him) said: "Come close, come close, come close," shuffling towards one another, until, when they had come close enough, he (peace and blessings be upon him) wrapped them in his sheet. Then he said: "O my Lord! This is my uncle and the full brother of my father, and these are the people of my household. Shield them from the Fire just as I have covered them with this sheet of mine." The narrator said: Then the threshold of the door and the walls of the house said Amin, saying: Amin, Amin, Amin.
