141. hadíth
وَ فِي رِوَايَةِ مُعَاوِيَةَ بْنِ وَهْبٍ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ فِي كَمْ يُؤْخَذُ اَلصَّبِيُّ بِالصِّيَامِ قَالَ «مَا بَيْنَهُ وَ بَيْنَ خَمْسَ عَشْرَةَ سَنَةً أَوْ أَرْبَعَ عَشْرَةَ سَنَةً فَإِنْ هُوَ صَامَ قَبْلَ ذَلِكَ فَدَعْهُ وَ لَقَدْ صَامَ اِبْنِي فُلاَنٌ قَبْلَ ذَلِكَ فَتَرَكْتُهُ».
In the narration of Mu'awiyah ibn Wahb, he said: "I asked Abu Abdullah (a.s) at what age a child should be required to fast. Imam (a.s) said: 'Between fourteen and fifteen years of age. If he fasts before that, let him be. My son so-and-so fasted before that age, and I left him to it.'"
