What was the Prophet Muhammad (peace be upon him) instructed to do when Itban bin Malik (saw) asked him to lead prayer at his house?
 Narrated Mahmud bin Rabi` Al-Ansari:                     `Itban bin Malik used to lead his people (tribe) in prayer and was a blind man, he said to Allah's Apostle , "O Allah's Apostle! At times it is dark and flood water is flowing (in the valley) and I am blind man, so please pray at a place in my house so that I can take it as a Musalla (praying place)." So Allah's Apostle went to his house and said, "Where do you like me to pray?" 'Itban pointed to a place in his house and Allah's Apostle, offered the prayer there.
