CHAPTER: The Adhan Of A Blind Man.
Narrated Bilal: The Messenger of Allah صلی اللہ علیہ وسلم said to Bilal: Do not call adhan until the dawn appears clearly to you in this way, stretching his hand in latitude. Abu Dawud said: Shaddad did not see Bilal.
Aishah reported: Ibn Umm Maktum was the muadhdhin of the Messenger of Allah صلی اللہ علیہ وسلم and he was blind.
