وَ رَوَى سَمَاعَةُ بْنُ مِهْرَانَ عَنْهُ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «يَجُوزُ صَدَقَةُ اَلْغُلاَمِ وَ عِتْقُهُ وَ يَؤُمُّ اَلنَّاسَ إِذَا كَانَ لَهُ عَشْرُ سِنِينَ.
Sama’a bin Mehran narrated from Imam عليه السلام that He said: "The charity given by a boy, his emancipation (freeing a slave), and leading people in prayer are permissible if he is ten years old."
