رَوَى عَبْدُ اَلصَّمَدِ بْنُ مُحَمَّدٍ عَنْ حَنَانِ بْنِ سَدِيرٍ عَنْ أَبِيهِ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: "دَخَلْتُ عَلَى مُحَمَّدِ بْنِ عَلِيٍّ اِبْنِ اَلْحَنَفِيَّةِ وَ قَدِ اُعْتُقِلَ لِسَانُهُ فَأَمَرْتُهُ بِالْوَصِيَّةِ فَلَمْ يُجِبْ" قَالَ "فَأَمَرْتُ بِطَسْتٍ فَجَعَلْتُ فِيهِ اَلرَّمْلَ فَوُضِعَ فَقُلْتُ لَهُ خُطَّ بِيَدِكَ فَخَطَّ وَصِيَّتَهُ بِيَدِهِ فِي اَلرَّمْلِ وَ نَسَخْتُ أَنَا فِي صَحِيفَةٍ".
Abd Al-Ṣamad ibn Muhammad narrated from Hanan ibn Sadir from his father, from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (a.s), who said: "I entered upon Muhammad ibn Ali ibn Al-Hanafiyya, and his tongue had become paralyzed. I instructed him to make his will, but he did not respond. So, I ordered a basin to be brought and filled it with sand. I said to him, 'Write with your hand,' and he wrote his will in the sand with his hand, and I copied it onto a scroll."
