It has been narrated on the authority of Ibn 'Umar who said: The Messenger of Allah ( صلی اللہ علیہ وسلم ) 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 bin 'Abdul ' Aziz (RA) 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.

This tradition has been handed down through a different chain Of transmitters with the following change in the wording:" I was fourteen years old and he thought me too young (to participate in the fight)."
