Narrated Mahmud bin Ar-Rabi':I remember Allah's Apostle and also the mouthful of water which he took from a bucket in our house and ejected (on me). I heard from ltban bin Malik Al-Ansari, who was one from Bani Salim, saying, "I used to lead my tribe of Bani Salim in prayer. Once I went to the Prophet and said to him, 'I have weak eye-sight and at times the rainwater flood intervenes between me and the mosque of my tribe and I wish that you would come to my house and pray at some place so that I could take that place as a place for praying (mosque). He said, "Allah willing, I shall do that." Next day Allah's Apostle along with Abu Bakr, came to my house after the sun had risen high and he asked permission to enter. I gave him permission, but he didn't sit till he said to me, "Where do you want me to pray in your house?" I pointed to a place in the house where I wanted him to pray. So he stood up for the prayer and we aligned behind him. He completed the prayer with Taslim and we did the same simultaneously."
