'Uqba b. Amir reported: We said to Allah's Messenger (may peace be upon him): You send us out and we come to the people who do not give us hospitality, so what is your opinion? Thereupon Allah's Messenger (may peace be upon him) said: If you come to the people who order for you what is befitting a guest, accept it; but if they do not. take from them what befits them to give to a guest.
