Khubayb bin Abd al-Rahman narrates from his aunt Unaysah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "When Ibn Umm Maktum (may Allah be pleased with him) gives the adhan at night, eat and drink until Bilal (may Allah be pleased with him) gives the adhan."
