Musannaf Ibn Abi Shaybah 9186 — Those who considered it recommended

Khubayb bin Abd al-Rahman said: I heard one of my paternal aunts, who had performed Hajj with the Prophet (peace and blessings be upon him), say that the Messenger of Allah (peace and blessings be upon him) said: "When Ibn Umm Maktum calls the adhan at night, keep eating and drinking until Bilal calls the adhan; and when Bilal calls the adhan at night, keep eating and drinking until Ibn Umm Maktum calls the adhan." She said: One of these two mu'adhdhins would climb up the minaret as the other came down, and we would hold on to him and say, "Stay as you are until we have eaten our pre-dawn meal."
