Abu Tha'laba al-Khushani told that he said, “Messenger of God, we travel about and when we come to Jews, Christians and Magians we can get nothing but their vessels.” He replied, “If you can get nothing else, wash them with water and then eat and drink out of them.”
Qabisa b. Hulb quoted his father as saying that he asked the Prophet about the food of the Christians, (a version saying it was a man who asked him), adding that it was a kind of food from which he kept aloof. He replied, “Let no doubt enter your breast by which you resemble Christianity.”*
*The general sense is that such food is allowable.
He told that he said, “Messenger of God, I shoot at game and find my arrow in it the next day.” He replied, “When you know your arrow killed it and see no mark of a beast of prey on the animal you may eat it.”
