‘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.
Abu Bakr b. Sulaiman b. Abu Hathma said that ‘Umar b. al-Khattab missed Sulaiman b. Abu Hathma at the Morning Prayer. In the morning ‘Umar went to the market, and Sulaiman’s house being between the mosque and the market, he met ash-Shifa’, Sulaiman’s mother, and said to her, “I did not see Sulaiman at the morning prayer.” She replied, “He spent the night in prayer and was overpowered by sleep.” Thereupon ‘Umar said, “I would rather be present with a company at the Morning Prayer than spend a night in prayer.”
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.”
