Buraydah reported: When the Messenger of Allah, peace and blessings be upon him, issued orders to a commander of an army or a company, he would personally command him to fear Allah and be good to the Muslims with them. Then, the Prophet would say, “March forward in the name of Allah and in the way of Allah. Fight those who deny Allah. March forward and do not embezzle the spoils, do not be treacherous, do not mutilate, and do not kill children. When you meet your enemy among the idolaters, call them to three options. If they respond to any of these, you must accept it and refrain from harming them. Thus, call them to Islam. If they answer you, accept it from them and refrain from harming them. Then, call them to relocate from their abodes to the abode of the emigrants. Inform them if they do that, they will have the privileges and duties of the emigrants. If they refuse to relocate, inform them they will be like the Bedouin Arabs among the Muslims under the rulings of Allah, the same as the believers, but they will have no share of the spoils unless they fight with the Muslims. If they refuse, ask them to pay tribute. If they answer you, accept it and refrain from harming them. If they refuse everything, then seek help from Allah and fight them.”

عَنْ بُرَيْدَةَ قَالَ كَانَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ إِذَا أَمَّرَ أَمِيرًا عَلَى جَيْشٍ أَوْ سَرِيَّةٍ أَوْصَاهُ فِي خَاصَّتِهِ بِتَقْوَى اللهِ وَمَنْ مَعَهُ مِنَ الْمُسْلِمِينَ خَيْرًا ثُمَّ قَالَ اغْزُوا بِاسْمِ اللهِ فِي سَبِيلِ اللهِ قَاتِلُوا مَنْ كَفَرَ بِاللهِ اغْزُوا وَلَا تَغُلُّوا وَلَا تَغْدِرُوا وَلَا تُمَثِّلُوا وَلَا تَقْتُلُوا وَلِيدًا وَإِذَا لَقِيتَ عَدُوَّكَ مِنَ الْمُشْرِكِينَ فَادْعُهُمْ إِلَى ثَلَاثِ خِصَالٍ فَأَيَّتُهُنَّ مَا أَجَابُوكَ فَاقْبَلْ مِنْهُمْ وَكُفَّ عَنْهُمْ ثُمَّ ادْعُهُمْ إِلَى الْإِسْلَامِ فَإِنْ أَجَابُوكَ فَاقْبَلْ مِنْهُمْ وَكُفَّ عَنْهُمْ ثُمَّ ادْعُهُمْ إِلَى التَّحَوُّلِ مِنْ دَارِهِمْ إِلَى دَارِ الْمُهَاجِرِينَ وَأَخْبِرْهُمْ أَنَّهُمْ إِنْ فَعَلُوا ذَلِكَ فَلَهُمْ مَا لِلْمُهَاجِرِينَ وَعَلَيْهِمْ مَا عَلَى الْمُهَاجِرِينَ فَإِنْ أَبَوْا أَنْ يَتَحَوَّلُوا مِنْهَا فَأَخْبِرْهُمْ أَنَّهُمْ يَكُونُونَ كَأَعْرَابِ الْمُسْلِمِينَ يَجْرِي عَلَيْهِمْ حُكْمُ اللهِ الَّذِي يَجْرِي عَلَى الْمُؤْمِنِينَ وَلَا يَكُونُ لَهُمْ فِي الْغَنِيمَةِ وَالْفَيْءِ شَيْءٌ إِلَّا أَنْ يُجَاهِدُوا مَعَ الْمُسْلِمِينَ فَإِنْ هُمْ أَبَوْا فَسَلْهُمُ الْجِزْيَةَ فَإِنْ هُمْ أَجَابُوكَ فَاقْبَلْ مِنْهُمْ وَكُفَّ عَنْهُمْ فَإِنْ هُمْ أَبَوْا فَاسْتَعِنْ بِاللهِ وَقَاتِلْهُمْ
