Assalam O alaikum I wanted to ask you about a question related to incest. So I have a relative whose now 16 and made a huge mistake the thing I\’m about to tell you is very disturbing so please excuse me so the thing started of when he was 12 his puberty I think hadn\’t started and his sister was 4 and his sexual desires took over him and he took off a bit of his trouser and his sisters and there his private touched her back but he didn\’t commit intercourse so is this still known to incest and has he lost his virginity astagfirullah and could you tell me how can he repent? JazakAllah
