Musannaf Ibn Abi Shaybah 9050 — A man performing voluntary prayer

Sayyiduna Itban bin Malik (may Allah be pleased with him) said: I said: "O Messenger of Allah, sometimes the floods prevent me from going to the mosque of my people. I would like you to come to my house some day and pray in a place, and I will take that place as a place of prayer." He (peace and blessings be upon him) said: "We will do so." So the next day the Prophet (peace and blessings be upon him) came to my house, bringing Sayyiduna Abu Bakr (may Allah be pleased with him) with him. He asked: "Which place do you want to make a place of prayer?" I pointed to a corner of the house, so he stood there. We formed a row behind him, and he led us in two rak'ahs.
