Narrated from Hazrat Anisah, "who participated in Hajj with the Prophet (peace be upon him)," that the Prophet (peace be upon him) said: "Ibn Umm Maktum gives the call to prayer during the night, so keep eating and drinking until Bilal gives the call to prayer." The narrator says that in fact, he was a blind man, he could not see, so he would not give the call to prayer until people started saying, "Give the call to prayer, you have brought the morning."
