Addressing (the people) Samurah b. Jundub reported the Messenger of Allah (ﷺ) as saying:
The adhan (call to prayer) of Bilal should not prevent you from taking a meal shortly before dawn, not does the whiteness of horizon (before dawn) in this way (vertically) until it spreads out horizontally. (DE)
