from his father who said: "Whenever the Messenger of Allah ﷺ dispatched a commander of an army he would exhort him personally; that he should have Taqwa of Allah, and regarding those of the Muslims who are with him; that he should be good to them. He would say: 'Fight in the Name of Allah and in Allah's curse. Fight those who disbelieve in Allah and fight, do not be treacherous, nor mutilate, nor kill a child."

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا بَعَثَ أَمِيرًا عَلَى جَيْشٍ أَوْصَاهُ فِي خَاصَّةِ نَفْسِهِ بِتَقْوَى اللَّهِ وَمَنْ مَعَهُ مِنَ الْمُسْلِمِينَ خَيْرًا فَقَالَ اغْزُوا بِسْمِ اللَّهِ وَفِي سَبِيلِ اللَّهِ قَاتِلُوا مَنْ كَفَرَ بِاللَّهِ اغْزُوا وَلاَ تَغُلُّوا وَلاَ تَغْدِرُوا وَلاَ تُمَثِّلُوا وَلاَ تَقْتُلُوا وَلِيدًا وَفِي الْحَدِيثِ قِصَّةٌ قَالَ وَفِي الْبَابِ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ وَشَدَّادِ بْنِ أَوْسٍ وَعِمْرَانَ بْنِ حُصَيْنٍ وَأَنَسٍ وَسَمُرَةَ وَالْمُغِيرَةِ وَيَعْلَى بْنِ مُرَّةَ وَأَبِي أَيُّوبَ
