Imam wrote in his letter to al-Ashtar when he appointed him governor of Egypt, 'Do not reject the peace to which your enemy may call you, and wherein the pleasure of Allah lies, for verily peace affords composure to your army, relief to you from your worries, and safety for the country. After the peace entreaty however, be extremely wary of your enemy, because often the enemy draws near in order to take advantage of your negligence. Therefore, act prudently and entertain good opinion about them, though aIways being on your guard.?
