Assalaamu alaykum. I have a question for my closed friend. At the age of 9 or 10 (3rd or 4th grade), he slept with his mother. Due to the bad society they live in, he learned about sexual intercourse in school etc., so one night, while he was sleeping with his mother, he touched the private part of his mother with lust (at the age mention above) while his mother was asleep. Recently, they heared about "Hurmat-e-Musaharat", so they are very depressed of thinking that the marriage of his parents is broken. He already repented for it, but due to Waswaas (devilish/obsessive whisperings), he cannot focus on his work or prayers and also dreamed of being intimate with his sister etc. He is of a reputable family here. I told him that this is only valid for adults and that he was not adult at that age, as mentioned (it happened about 15 year ago), but he needs a fatwa from a Mufti. Is his parents' marriage broken or not? Please answer as soon as possible.

All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

What the boy did has no effect on his mother's marriage. He should fill his time with what benefits him (in this worldly life and the Hereafter) instead and ignore these illusions and satanic whispers that distract him and disturb his life.

Allah knows best.
