Addressing (the people) Samurah bin 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.

Narrated Anas ibn Malik: A man from Banu Abdullah ibn Kab brethren of Banu Qushayr (not Anas ibn Malik, the well-known Companion), said: A contingent from the cavalry of the Messenger of Allah ﷺ raided us. I reached (for he said went) to the Messenger of Allah ﷺ who was taking his meals. He said: Sit down, and take some from this meal of ours. I said: I am fasting, he said: Sit down, I shall tell you about prayer and fasting. Allah has remitted half the prayer to a traveller, and fasting to the traveller, the woman who is suckling an infant and the woman who is pregnant, I swear by Allah, he mentioned both (i. e. suckling and pregnant women) or one of them. I was grieved for not taking the food of the Messenger of Allah ﷺ.
