Hadith.906 - Bilal used to call to prayer after the morning (Fajr), and The Prophet صلى الله عليه وعلى آله وسلم said:
"Indeed, Ibn Umm Maktum calls to prayer during the night, so if you hear his adhan, eat and drink until you hear the adhan of Bilal."
The general populace altered this narration and claimed that he (the Prophet) said:
"Indeed, Bilal calls to prayer during the night, so if you hear his adhan, eat and drink until you hear the adhan of Ibn Umm Maktum."
