To Egyptians after the appointment of Malik al-Ashtar as their governor

Now, I have sent to you a man from among the servants of Allāh who allows himself no sleep in days of danger, nor does he shrink from the enemy at critical moments. He is severer on the wicked than a blazing fire. He is Mālik ibn al-Ḥārith, our brother from (the tribe of) Madhḥij.
