English translation
1361. Nāfi' narrated that Ibn 'Umar said: "I was reviewed before the Messenger of Allāh ﷺ in the army, and I was fourteen years old, but he did not accept me. Then I was reviewed before him in the army later while I was fifteen years old, and he accepted me." Nāfi' said: "I narrated this Hadīth to 'Umar bin 'Abdul-'Azīz and he said: 'This is the limit that distinguishes between childhood and adulthood.' Then he wrote to give salaries to whoever reached fifteen years old." (Another chain) from Nāfi', from Ibn 'Umar from the Prophet ﷺ, and it is similar, but he did not mention in it that 'Umar bin 'Abdul-'Azīz wrote that this is the limit that distinguishes between youth and childhood and adulthood. In his narration, Ibn 'Uyainah said (that Nāfi' said): "I narrated it to 'Umar bin 'Abdul-'Azīz and he said: 'This is the limit that distinguishes between children and soldiers.'" (Ṣaḥīḥ)
