3ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ النَّضْرِ بْنِ سُوَيْدٍ عَنْ يَحْيَى الْحَلَبِيِّ عَنِ ابْنِ مُسْكَانَ عَنْ زُرَارَةَ قَالَ سَأَلْتُ أَبَا جَعْفَرٍ (عَلَيْهِ الْسَّلام) عَنِ الْوِلْدَانِ فَقَالَ سُئِلَ رَسُولُ الله (صلّى اللهُ عَلَيْهِ وَآلِه) عَنِ الْوِلْدَانِ وَالأطْفَالِ فَقَالَ الله أَعْلَمُ بِمَا كَانُوا عَامِلِينَ.
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Nadr ibn al-Suwayd from Yahya al-Halabiy from ibn Muskan from Zurarah who has said the following: “I asked abu Ja‘far (a.s.), about the children, and he said, ‘The Messenger of Allah was asked about the children and infants, and he replied, “Allah knows best about what they had been doing.’””
