أَمَّا بَعْدُ، فَإِنَّ مِصْرَ قَدِ افْتُتِحَتْ، وَمُحَمَّدُ بْنُ أَبِي بَكْرٍ رَحِمَهُ اللهُ قَدِ اسْتُشْهِدَ، فَعِنْدَ اللهِ نَحْتَسِبُهُ، وَلَداً نَاصِحاً، وَعَامِلًا كَادِحاً، وَسَيْفاً قَاطِعاً، وَرُكْناً دَافِعاً. وَقَدْ كُنْتُ حَثَثْتُ النَّاسَ عَلَى لَحَاقِهِ، وَأَمَرْتُهُمْ بِغِيَاثِهِ قَبْلَ الْوَقْعَةِ، وَدَعَوْتُهُمْ سِرّاً وَجَهْراً، وَعَوْداً وَبَدْءاً، فَمِنْهُمُ الْآتِي كَارِهاً، وَمِنْهُمُ الْمُعْتَلُّ كَاذِباً، وَمِنْهُمُ الْقَاعِدُ خَاذِلًا.
Now then, Egypt has, been conquered and Muḥammad ibn Abī Bakr, may Allāh have mercy on him, has been martyred. We seek his reward from Allāh. 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.
