This is a sensitive topic and I am sure many of us (including me) were never educated about sex, puberty, adolescence etc. In fact in Muslim society, anything slighly related to the opposite gender (for a male child) is strictly kept secret. A male child may never know how babies are born or that girls have menses or what masturbation is or why their body changes during adolescence etc.
I have heard from some religious people that the responsibility lies with the parents to educate their children about such topics including adolescence, masturbation etc. They say, if the child commits a sin out of ignorance, then the parents are to be blamed and they will be punished for it in the hereafter. Similarly in the case of Muslims being married late, if the child commits a sin before marriage, the responsibility lies on the parents because they should have got his/her child married on time so he had no excuse to sin.
I am looking for credible evidence that says:
- Who's responsibility it is, from an Islamic point of view, to teach the child about sex, adolescence, molestation etc etc (parents, school, sibling, mosque, someone else?)?
- Is it true that if a child commits a sin because he was not made aware of the sin, the parents are to be held accountable for it?
- Bonus question: Islamically what age is considered a suitable age in Islam where parents or someone can start being educated on these matter? I have it it should before commencement of adolescence (because once a adolescence starts, the child may already commit sin) but someone one may argue it should be at start of adolescence.
