Arabic hadith text
أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم عَرَضَهُ يَوْمَ أُحُدٍ وَهُوَ ابْنُ أَرْبَعَ عَشْرَةَ سَنَةً فَلَمْ يُجِزْهُ وَعَرَضَهُ يَوْمَ الْخَنْدَقِ وَهُوَ ابْنُ خَمْسَ عَشْرَةَ سَنَةً فَأَجَازَهُ .
Translation
Ubaydullah bin Sa'id informed us; Yahya narrated to us, from Ubaydullah, who said: Nafi informed me, from Ibn Umar, that the Messenger of Allah presented him for assessment at Uhud when he was fourteen years old and did not approve him; he presented him at the Battle of the Trench when he was fifteen years old and approved him.
