It is narrated from Hazrat Buraidah (may Allah be pleased with him) that whenever the Noble Prophet, peace and blessings be upon him, appointed someone as the commander of a detachment or an army, he would especially advise him to fear Allah regarding himself and would emphasize that he treat the Muslims who were with him in the best manner. Then he would say: Fight in the name of Allah, in the way of Allah, and fight those who disbelieve in Allah. When you meet your enemy from among the polytheists, invite them to three things. If they accept any one of them, accept it from them and refrain from fighting them. First, invite them to Islam. If they accept, then accept it from them. Then invite them to migrate from their land to the land of the Muhajireen, and inform them that if they do so, they will have the same rights and responsibilities as the Muhajireen. If they refuse and prefer to remain in their own land, then inform them that they will be considered like the Bedouin Muslims; the commands of Allah will apply to them as they apply to all Muslims, but they will not have any share in the spoils of war unless they participate in jihad with the Muslims. If they refuse this, then invite them to pay the jizya. If they accept, then accept it from them and refrain from fighting them. But if they refuse even this, then seek help from Allah and fight them.
