Part of instructions to his marshal when Imam Ali (a) sent him to a battle [^1] ومن وصية وصّى بها(عليه السلام) جيشاً بعثه إلى العدو When you proceed towards the enemy or he proceeds towards you, the position of your force should be on the approaches high ground or on the edges of mountains or the bends of rivers, so that it may serve you as a help and a place to return to. Your encounter should be from one side or two sides.
Place watchers on the peaks of mountains and the raised sides of the high ground so that the enemy may not approach you from any place, whether of danger or safety. And know that the vanguard of an army serves as their eyes, and the eyes of the vanguard are their informers. Beware of dispersal. When you halt do so together and when you move you should move together. When night comes fix your spears in a circle and do not sleep except for dozing or napping.
[^1]: When Amir al-mu'minin put Ziyad ibn an-Nadr al-Harithi and Shurayh ibn Hani al-Harithi in command of contingents of eight thousand and four thousand strong at the camp of an-Nukhaylah and ordered them to advance towards Syria (ash-Sham), some dispute arose between them about their ranks, of which they apprised Amir al-mu'minin and wrote letters of complaints about each other.
In reply, Amir al-mu'minin wrote to them that when they marched jointly the command of the whole force would be with Ziyad ibn an-Nadr al-Harithi and when they marched separately each would be in command of the force over which he had been placed. In this letter Amir al-mu'minin also wrote for them certain instructions.
