Q: In Bahishti Zewar, there are many masaail that speak about a husband who can have sexual intercourse with a minor. There was 1 certain masa'ala that (if a husband has sexual intercourse with a minor where there is a fear of her vaginal tissues coming together then ghusl is not fard upon her pg. 74 quoted briefly).

Mas'ala was quite graphic and gave me a headache just by thinking about it. My question is, won't that be considered as paedophilia. Does Islam really allow having intercourse with minors. If not then why are these masaail mentioned in Fiqhi books. Your detailed explanation will highly be appreciated.
