Mishkat al-Masabih #1017

‘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 Dawud and Nasa’i transmitted it.
