It is narrated from Sayyiduna Mahmood bin Labeed Ansari (may Allah be pleased with him) that Sayyiduna Utban bin Malik (may Allah be pleased with him) used to lead his people in prayer, and his eyesight was weak. He said to the Messenger of Allah (peace and blessings of Allah be upon him): Sometimes there is darkness, or water, or a flood, and my eyesight is weak, so please pray at a place in my house so that I may take that spot as my place of prayer. So the Messenger of Allah (peace and blessings of Allah be upon him) came and said: "Where would you like me to pray?" He pointed out a place, and the Prophet (peace and blessings of Allah be upon him) prayed there.
