Now then, Egypt has been conquered and Muhammad ibn Abi Bakr, may Allah have mercy on him, has been martyred. We seek his reward from Allah. He was a son who was a well-wisher, a hard worker, a sharp sword and a bastion of defence. I had roused the people to join him and ordered them to reach him to help before this incident. I called to them secretly as well as openly repeatedly. Some of them came half-heartedly, some put up false excuses and some sat away leaving me. I ask Allah the Sublime, to give me early relief from them, for by Allah, had I not been yearning to meet the enemy for martyrdom and not prepared myself for death, I would not have liked to be with these people for a single day nor ever to face the enemy with them.
