Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah that the Messenger of Allah, may Allah bless him and grant him peace, said, " Bilal (RA) calls the adhan in the night, so eat and drink until Ibn Umm Maktum calls the adhan." Ibn Umm Maktum was a blind man who did not call the adhan until someone said to him, "The morning has come. The morning has come."
