It was narrated that Safwan bin ‘Assil said:`“The Messenger of Allah ( صلی اللہ علیہ وسلم ) sent us in a military detachment and said: ‘Go in the Name of Allah, and in the cause of Allah. Fight those who disbelieve in Allah. Do not mutilate, do not be treacherous, do not steal from the spoils of war, and do not kill children.’”

Buraidah (may Allah be pleased with him) reports that whenever the Messenger of Allah (peace and blessings of Allah be upon him) appointed someone as commander over a military detachment, he would personally advise him to fear Allah and to treat his fellow Muslims well, and he would say: "Fight in the way of Allah in the name of Allah, fight those who disbelieve in Allah, do not be treacherous, do not commit breach of trust (regarding the spoils of war), do not mutilate, and do not kill any child. When you meet your enemy from among the polytheists, invite them to three things. Whichever of these they accept, accept it from them and refrain from fighting them. (First of all) invite them to Islam. If they accept, then accept their Islam and refrain from killing them. Then invite them to leave their homes and dwell with the Muhajirun, and inform them that if they do so, they will have the same rights as the Muhajirun, and the same law of crime and punishment will apply to them as applies to the Muhajirun. If they refuse to migrate, then inform them that their status will be like that of the Bedouin Muslims, and the commands of Allah that apply to Muslims will also apply to them, but they will have no share in the spoils of war or in the wealth acquired from the disbelievers without fighting, unless they fight alongside the Muslims. If they refuse to accept Islam, then demand the payment of jizyah from them. If they agree to pay jizyah, accept it from them and refrain from fighting them. If they refuse, then seek help from Allah (for victory) and fight them. If you besiege a fortress and its people want you to grant them the protection of Allah and His Prophet, do not grant them the protection of Allah and His Prophet, but grant them your own protection, or that of your father and your companions, for you can break your own protection or that of your father more easily than you can break the protection of Allah and His Messenger. If you besiege a fortress and they want to surrender on the judgment of Allah, do not let them surrender on the judgment of Allah, but let them surrender on your own judgment, for you do not know whether you will be able to carry out Allah's judgment regarding them or not." ‘Alqamah says: I narrated this hadith to Muqatil bin Hayyan, and he said: Muslim bin Hizam narrated it to me, and Muslim narrated it from Nu’man bin Muqarrin (may Allah be pleased with him), and he narrated it from the Prophet (peace and blessings of Allah be upon him) in the same manner.
