Ibn'Abbas reported the Prophet as saying, “If anyone hears the summons and does not respond to it, he is not credited with having prayed unless he has some excuse.”
‘Uthman b. ‘Affan reported God’s Messenger as saying, “If the adhan is called when anyone is in the mosque and he goes out for any other reason than some necessary purpose, not intending to return, he is a hypocrite.”
‘Abdallah b. Umm Maktum said, “Messenger of God, there are many venomous creatures and wild beasts in Medina, and I am blind, so are you able to grant me any licence?” He asked whether he could hear the call, “Come to prayer. Come to salvation,” and when he replied that he could, he said, “Then you must come,” and he gave him no indulgence.
Abush Sha'tha’ said that a man went out of the mosque after the adhan had been called in it, and Abu Huraira said, “This man has disobeyed Abul Qasim.”
