Sayyiduna Uqbah bin Amir (may Allah be pleased with him) says: We said: O Messenger of Allah (peace and blessings be upon him)! You send us to a people, and if they do not host us, (what then)? The Messenger of Allah (peace and blessings be upon him) said: "If you stay as guests with a people and they arrange for you the hospitality that is fitting, then accept it; and if they do not arrange hospitality, then you may take from them the due right of hospitality."
