منة

a boy is taken to task over prayers when he is seven years old, and a woman does not cover her hair from him until he begins to have nocturnal emissions.

“Abu ‘Abd Allah (a.s.), has said, ‘The orphan-hood of an orphan is over when he experiences wet-dream, and that is the time when he reaches manhood but if he experiences wet- dream and does not have proper understanding because of dimwittedness or weakness, then his guardian must keep his assets for him.’”

the termination of the orphanhood of the orphan is by nocturnal emission and it is considered his maturity, however if he begins to have nocturnal emissions but signs of intellectual maturity are not detected from him such that he is foolhardy or mentally incapacitated then his guardian withholds from handing over his wealth to him.
