Jami` at-Tirmidhi 715
جامع الترمذي#715SahihAnas bin Malik, a man from Banu Abdullah bin Ka'b said:"Some cavalry man of the Messenger of Allah came galloping upon us, so I came to the Messenger of Allah and found him having lunch. He said: "Come and eat." I said: 'I am fasting.' So he said: 'Come and I will narrate to you about the fast - or fasting. Indeed Allah Most High lifted (the fast and) half of the Salat from the traveler, and (He lifted) the fast - or fasting - from the pregnant person, or the breast-feeding person.' And by Allah! The Prophet said both of them or one of them. So woe to me! For I did not eat from the meal of the Prophet
