Abu Dawud Book 7, Hadith Number 2402.

Chapter : Not known.

Narated By Anas ibn Malik : A man from Banu Abdullah ibn Ka’b brethren of Banu Qushayr (not Anas ibn Malik, the well-known Companion), said: A contingent from the cavalry of the Apostle of Allah (PBUH) raided us. I reached (for he said went) to the Apostle of Allah (PBUH) 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 Apostle of Allah (PBUH).
