A child who commits a crime that is subject to a had (punishment)

Narrated Atiyyah al-Qurazi:

I was among the captives of Banu Qurayzah. They (the Companions) examined us, and those who had begun to grow hair (pubes) were killed, and those who had not were not killed. I was among those who had not grown hair.

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، أَخْبَرَنَا عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ، حَدَّثَنِي عَطِيَّةُ الْقُرَظِيُّ، قَالَ كُنْتُ مِنْ سَبْىِ بَنِي قُرَيْظَةَ فَكَانُوا يَنْظُرُونَ فَمَنْ أَنْبَتَ الشَّعْرَ قُتِلَ وَمَنْ لَمْ يُنْبِتْ لَمْ يُقْتَلْ فَكُنْتُ فِيمَنْ لَمْ يُنْبِتْ .

The tradition mentioned above has also been transmitted by ‘Abd al- Malik b. ‘Umar through a different chain of narrators. This version has:
They uncovered my private parts, and when they found that the hair had not begun to grow they put me among the captives.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، بِهَذَا الْحَدِيثِ قَالَ فَكَشَفُوا عَانَتِي فَوَجَدُوهَا لَمْ تَنْبُتْ فَجَعَلُونِي فِي السَّبْىِ .

Ibn ‘Umar said:
He was presented before the prophet ﷺ on the day of Uhd when he was fourteen years old, but he did not allow him (to participate in the battle). He was again presented before him on the day of Khandaq when he was fifteen years old, Then he allowed him.

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ ﷺ عُرِضَهُ يَوْمَ أُحُدٍ وَهُوَ ابْنُ أَرْبَعَ عَشْرَةَ سَنَةً فَلَمْ يُجِزْهُ وَعُرِضَهُ يَوْمَ الْخَنْدَقِ وَهُوَ ابْنُ خَمْسَ عَشْرَةَ سَنَةً فَأَجَازَهُ .
