Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: Once, Sayyiduna Bilal (may Allah be pleased with him) gave the adhan before true dawn, so the Noble Prophet (peace and blessings be upon him) became displeased. He instructed him to announce: "Indeed, the servant had fallen asleep." Sayyiduna Bilal (may Allah be pleased with him) felt very sorry about this. In this narration, the narrator named 'Amir made a mistake; the correct narration is the one that has already passed, which is transmitted from Nafi' on the authority of the muezzin of Sayyiduna Umar (may Allah be pleased with him) through the narrator named Ibn Harb.
