Anas continued, "I took it, and I found the Messenger of Allah (ﷺ) sitting in the mosque with some people. I watched them. The Messenger of Allah (ﷺ) said, 'Did Abu Talha send you?' I replied, 'Yes.' He said, 'For food?' I said, 'Yes.' The Messenger of Allah (ﷺ) said to those with him, 'Let us go.' He set off and I went among them until I came to Abu Talha and told him. Abu Talha said, 'Umm Sulaym! The Messenger of Allah (ﷺ) has brought people and we have no food. What shall we give them to eat?' She said, 'Allah and His Messenger know best.' "
Anas continued, "Abu Talha went out and met the Messenger of Allah (ﷺ) and the Messenger of Allah (ﷺ) approached with Abu Talha until they entered. The Messenger of Allah (ﷺ) said, 'Come now, Umm Sulaym, what have you got?' She brought out bread. The Messenger of Allah (ﷺ) ordered it to be broken into pieces, and Umm Sulaym squeezed out onto it a container of clarified butter which she had seasoned. Then the Messenger of Allah (ﷺ) said whatever Allah wished him to say, and said, 'Will you give permission for ten of them to come in?' He gave them permission, and they ate until they were full and then left. He said, 'Give permission to ten more.' He gave them permission, and they ate until they were full and left. Then he said, 'Give permission to ten more.' He gave them permission and they ate until they were full and left. Then he said, 'Give permission to ten more.' He gave permission and they ate until they were full and left. There were seventy or eighty men."
