Sayyidah Aishah Siddiqah (may Allah be pleased with her) states: Sayyiduna Bilal (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) to inform him of the morning prayer and found him asleep. He said, "Prayer is better than sleep." So these words were retained in (the adhan of) the morning prayer.
Imam al-Tabarani recorded this narration in al-Mu'jam al-Awsat. Its chain contains a narrator, Salih bin Abi al-Akhdar, about whose use as evidence there is disagreement; no one has accused him of lying.
