Tahdhīb al-Aḥkām|Volume 4|Book 2|Chapter 33
وَ مَا رَوَاهُ مُحَمَّدُ بْنُ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: أَنَّهُ سُئِلَ عَنِ اَلصَّبِيِّ مَتَى يَصُومُ قَالَ» إِذَا أَطَاقَهُ«.
And what Muhammad ibn Muslim narrated from Abu Ja’far عليه السلام, peace be upon him:
Imam عليه السلام was asked about ‘the boy, when does he (made to) fast?’ Imam عليه السلام said: “When he is able to bear it.”
