'Abdullah bin Umar (may Allah be pleased with them both) says: I was presented before the Messenger of Allah (peace be upon him) in an army, and I was fourteen years old, but he did not accept me (for fighting in jihad). Then I was presented before him in an army the following year, and I was fifteen years old, so he accepted me (in the army). Nafi' says: I narrated this hadith to Umar bin Abdul Aziz, and he said: This is the limit between minor and major. Then he issued a decree that whoever reaches fifteen years should be given a share from the spoils of war .
