What did the Prophet Muhammad (saw) tell the blind man when he asked for permission to say prayer at his house?
 Abu Huraira reported:                      There came to the Apostle of Allah (may peace be upon him) a blind man and said: Messenger of Allah, I have no one to guide me to the mosque. He, therefore, asked. Allah's Messenger (may peace be upon him) permission to say prayer in his house. He (tee Holy Prophet) granted him permission. Then when the man turned away he called him and said: Do you hear the call to prayer? He said: Yes. He (the Holy Prophet then) said: Respond to it.
