Mahmud bin Rabi' Al-Ansari, who remembered that the Messenger of Allah spat a mouthful of water from a bucket into a well that belonged to them, narrated that :
Itban bin Malik As-Salimi who was the chief of his people Banu Salim and had participated in (the battle of) Badr with the Messenger of Allah said: "I came to the Messenger of Allah and said: 'O Messenger of Allah, my sight is failing and the flood comes and prevents me from reaching the mosque of my people, and it is too hard for me to cross the water. Do you think you could come and perform prayer in my house in a place which I can then take as a place of prayer?' He said: 'I will do that.' The following day, the Messenger of Allah and Abu Bakr came, when the heat of the day had grown intense. He asked permission to enter, and I gave him permission. He did not sit down until he said: 'Where would you like me to perform prayer for you in your house?' I showed him the place where I wanted him to pray, so the Messenger of Allah stood and we lined up behind him, and he led us in praying two Rak'ah (units). Then I asked him to stay and eat some Khazirah that had been prepared for them.'"
