[Machine] The Messenger of Allah ﷺ presented me on the day of Uhud when I was fourteen years old and he made me walk with the youths. Then, on the day of Khandaq, he presented me when I was fifteen years old. He said, "Give him permission." 'Ubaidullah said, 'Umar ibn Abd al-Aziz wrote that permission should be granted in obligatory matters for someone who is fifteen years old.' 'Ubaidullah said, 'I do not see any benefit except in narrating with this.'  

البيهقي:١١٣٠١وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أنبأ أَبُو الْفَضْلِ بْنُ إِبْرَاهِيمَ ثنا أَحْمَدُ بْنُ سَلَمَةَ ثنا مُحَمَّدُ بْنُ الْمُثَنَّى وَمُحَمَّدُ بْنُ بَشَّارٍ قَالَا ثنا عَبْدُ الْوَهَّابِ الثَّقَفِيُّ ثنا عُبَيْدُ اللهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ

عَرَضَنِي رَسُولُ اللهِ ﷺ يَوْمَ أُحُدٍ وَأَنَا ابْنُ أَرْبَعَ عَشْرَةَ سَنَةً فَاسْتَصْغَرَنِي وَرَدَّنِي مَعَ الْغِلْمَانِ فَلَمَّا كَانَ يَوْمُ الْخَنْدَقِ عَرَضَنِي وَأَنَا ابْنُ خَمْسَ عَشْرَةَ قَالَ فَأَجَازَنِي قَالَ عُبَيْدُ اللهِ وَكَتَبَ عُمَرُ بْنُ عَبْدِ الْعَزِيزِ أَنْ أَجِيزُوا فِي الْفَرْضِ ابْنَ خَمْسَ عَشْرَةَ قَالَ عُبَيْدُ اللهِ لَا أَرَى نَافِعًا إِلَّا حَدَّثَهُ بِهَذَا  

رَوَاهُ مُسْلِمٌ فِي الصَّحِيحِ عَنْ مُحَمَّدِ بْنِ الْمُثَنَّى وَفِي حَدِيثِ حَمَّادِ بْنِ زَيْدٍ عَنْ عُبَيْدِ اللهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللهِ ﷺ قَبِلَ ابْنَ عُمَرَ وَرَافِعَ بْنَ خَدِيجٍ يَوْمَ الْخَنْدَقِ وَهُمَا ابْنَا خَمْسَ عَشْرَةَ سَنَةً رَوَاهُ إِسْحَاقُ عَنْ رَوْحٍ عَنْهُ

The Messenger of Allah ﷺ inspected me on the battlefield on the Day of Uhud, and I was fourteen years old. He did not allow me (to take part in the fight). He inspected me on the Day of Khandaq-and I was fifteen yearsold, and he permitted me (to fight), Nafi' said: I came to 'Umar b. 'Abd al-'Aziz who was then Caliph, and narrated this tradition to him. He said: Surely, this is the demarcation between a minor and a major. So he wrote to his governors that they should pay subsistence allowance to one who was fifteen years old, but should treat those of lesser age among children. (Using translation from Muslim 1868a)
