Hadith 2387- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ الْوَشَّاءِ عَنْ عَبْدِ اللهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ إِذَا بَلَغَ أَشُدَّهُ ثَلاثَ عَشْرَةَ سَنَةً وَدَخَلَ فِي الأرْبَعَ عَشْرَةَ وَجَبَ عَلَيْهِ مَا وَجَبَ عَلَى الْمُحْتَلِمِينَ احْتَلَمَ أَوْ لَمْ يَحْتَلِمْ كُتِبَتْ عَلَيْهِ السَّيِّئَاتُ وَكُتِبَتْ لَهُ الْحَسَنَاتُ وَجَازَ لَهُ كُلُّ شَيْءٍ إِلا أَنْ يَكُونَ ضَعِيفاً أَوْ سَفِيهاً.
7. A number of our people have narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Washsha’ from ‘Abd Allah ibn Sinan who has narrated the following: “Abu ‘Abd Allah (a.s.), has said, ‘When a boy becomes strong when he is thirteen years old and has entered in his fourteenth, it becomes obligatory on him what is obligatory on those who experience wet-dream, regardless, he experiences wet-dream or not. Good deeds are written for him and all (lawful) things are permissible for him unless he is weak or dimwitted.’”
