Q: Does a boy who is not baaligh (physically mature) and around 12 or 13 years old become baaligh if he masturbates (if some liquid came out)?
A: It is recorded that the earliest that a male can become Baaligh is when he completes 12 Islamic years in age. (Jaami’u Ahkaamis Sighaar V1 P34). Thus this boy will consider himself as Baaligh and all the laws of Shari’ah will be applicable to him.
Allah Ta’aala knows best.
