Does one sin for having drawn pictures of girls, cartoon scenes, and animals in his youth, without his knowledge of the impermissibility of that?

Allah has lifted the pen from the child until he reaches maturity, from the sleeper until he awakens, and from the insane until he regains sanity. Similarly, He has lifted accountability from the Ummah for mistakes, forgetfulness, and that which they are compelled to do. Forgetfulness is like ignorance, and whoever commits a forbidden act out of ignorance of its prohibition incurs no blame. Therefore, what occurred in terms of drawing animate beings before puberty or before knowing its prohibition incurs no accountability. And whoever repents from his sin, Allah accepts his repentance.
