8- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِي مُحَمَّدٍ الْمَدَائِنِيِّ عَنْ عَلِيِّ بْنِ حَبِيبٍ بَيَّاعِ الْهَرَوِيِّ قَالَ حَدَّثَنِي عِيسَى بْنُ زَيْدٍ عَنْ أَبِي عَبْدِ اللهِ قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ صَلَوَاتُ اللهِ عَلَيْهِ يَثَّغِرُ الصَّبِيُّ لِسَبْعٍ وَيُؤْمَرُ بِالصَّلاةِ لِتِسْعٍ وَيُفَرَّقُ بَيْنَهُمْ فِي الْمَضَاجِعِ لِعَشْرٍ وَيَحْتَلِمُ لأرْبَعَ عَشْرَةَ وَيَنْتَهِي طُولُهُ لإحْدَى وَعِشْرِينَ سَنَةً وَيَنْتَهِي عَقْلُهُ لِثَمَانٍ وَعِشْرِينَ إِلا التَّجَارِبَ.
8. A number of our people have narrated from Ahmad ibn Muhammad from abu Muhammad al-Mada'iniy from Ali ibn Habib, Bayya’ al-Harawiy, who has said that ‘Isa ibn Zayd narrated from Abu ‘Abdillah who has said, “Amir al-Mu’minin has said, ‘A child teethes at the seventh year; he must be instructed to perform Salat (prayer) at the ninth; their bed must be separated at the tenth; experiences wet-dream at the fourteenth; his growth stops at twenty-one and growth of his reasoning ability stops at twenty-eight except experience.’”
