فَالْجُنُودُ، بِإِذْنِ اللهِ، حُصُونُ الرَّعِيَّةِ، وَزَيْنُ الْوُلَاةِ، وعِزُّ الدِّينِ، وَسُبُلُ الْأَمْنِ، وَلَيْسَ تَقُومُ الرَّعِيَّةُ إِلَّا بِهِمْ. ثُمَّ لَا قِوَامَ لِلْجُنُودِ إِلَّا بِمَا يُخْرِجُ اللهُ لَهُمْ مِنَ الْخَرَاجِ الَّذِي يَقْوَوْنَ بِهِ عَلَى جِهَادِ عَدُوِّهِمْ، وَيَعْتَمِدُونَ عَلَيْهِ فِيمَا يُصْلِحُهُمْ، وَيَكُونُ مِنْ وَرَاءِ حَاجَتِهِمْ.
Now the army is, by the will of Allāh, the fortress of the subjects, the ornament of the ruler, the strength of the religion and the means of peace. The subjects cannot exist without them while the army can be maintained only by the funds fixed by Allāh in the revenues, through which they acquire the strength to fight the enemies, on which they depend for their prosperity, and with which they meet their needs.
