 ١٦ـ إِسْحَاقُ قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ الْحَسَنِ بْنِ شَمُّونٍ قَالَ حَدَّثَنِي أَحْمَدُ بْنُ مُحَمَّدٍ قَالَ كَتَبْتُ إِلَى أَبِي مُحَمَّدٍ (عَلَيْهِ السَّلام) حِينَ أَخَذَ الْمُهْتَدِي فِي قَتْلِ الْمَوَالِي يَا سَيِّدِي الْحَمْدُ لله الَّذِي شَغَلَهُ عَنَّا فَقَدْ بَلَغَنِي أَنَّهُ يَتَهَدَّدُكَ وَيَقُولُ وَالله لاجْلِيَنَّهُمْ عَنْ جَدِيدِ الارْضِ فَوَقَّعَ أَبُو مُحَمَّدٍ (عَلَيْهِ السَّلام) بِخَطِّهِ ذَاكَ أَقْصَرُ لِعُمُرِهِ عُدَّ مِنْ يَوْمِكَ هَذَا خَمْسَةَ أَيَّامٍ وَيُقْتَلُ فِي الْيَوْمِ السَّادِسِ بَعْدَ هَوَانٍ وَاسْتِخْفَافٍ يَمُرُّ بِهِ فَكَانَ كَمَا قَالَ (عَلَيْهِ السَّلام )
 16. Ishaq has said that Muhammad ibn al-Hassan Shammun has said that Ahmad ibn Muhammad narrated to me the following. “I wrote to abu Muhammad  when al-Muhtadi had began to kill the Turkish Mawali (slave or supporters). My master, we thank Allah for diverting his (al-Muhtadi’s) attention from us. I have heard that he had threatened you and has said, By Allah, I will wipe them out from the face of the earth.” Abu Muhammad  sent in response with his own signature. “This will be much shortening to his life. Count five days from today. On the sixth day he will be killed with humiliation and insults that he will go through.” It then happned exactly as he had said.”
