A blind man came to the Prophet (ﷺ) and said, "O Messenger of Allah, I have no guide to take me to the mosque." He [the Prophet (ﷺ)] therefore permitted him (to pray at his house), then when the man turned away the Prophet (ﷺ) called him and asked, "Can you hear the Adhan (call) for prayer?" He answered, "Yes". He [the Prophet (ﷺ)] said, "Then respond to it." [Reported by Muslim].
