Hadith 4:57
Sufyan ibn Uyaynah narrated to us, from al-Zuhri, from Salim, from his father, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, Bilal calls the adhan at night, so eat and drink until Ibn Umm Maktum calls the adhan."
حدثنا سفيان بن عيينة عن الزهري عن سالم عن أبيه ان رسول الله صلى الله عليه وسلم قال ان بلالا يؤذن بليل فكلوا واشربوا حتى يؤذن بن أم مكتوم
