 ١٧ـ إِسْحَاقُ قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ الْحَسَنِ بْنِ شَمُّونٍ قَالَ كَتَبْتُ إِلَى أَبِي مُحَمَّدٍ (عَلَيْهِ السَّلام) أَسْأَلُهُ أَنْ يَدْعُوَ الله لِي مِنْ وَجَعِ عَيْنِي وَكَانَتْ إِحْدَى عَيْنَيَّ ذَاهِبَةً وَالاخْرَى عَلَى شَرَفِ ذَهَابٍ فَكَتَبَ إِلَيَّ حَبَسَ الله عَلَيْكَ عَيْنَكَ فَأَفَاقَتِ الصَّحِيحَةُ وَوَقَّعَ فِي آخِرِ الْكِتَابِ آجَرَكَ الله وَأَحْسَنَ ثَوَابَكَ فَاغْتَمَمْتُ لِذَلِكَ وَلَمْ أَعْرِفْ فِي أَهْلِي أَحَداً مَاتَ فَلَمَّا كَانَ بَعْدَ أَيَّامٍ جَاءَتْنِي وَفَاةُ ابْنِي طَيِّبٍ فَعَلِمْتُ أَنَّ التَّعْزِيَةَ لَهُ.
 17. Ishaq has said that Muhammad ibn al-Hassan Shammun narrated to me the following. “I wrote to abu Muhammad  requesting him to pray for because of the pain that I suffered in my eyes. One of my eye had gone and the other was about to go. He wrote back to me in reply, “Allah has kept your eye for you.” My painful eye then recovered. He had signed at the end with these words, “May Allah, grant you good rewards and best recompense.” I became sad and I did not know anyone just passed away from my family. After a few days I received information of the death of my son, Tayyib. I then realized what for his condolences to me were.”
