Fuqahaa explaining the parameters of Deen

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.

Replying to the azaan of two masjids

Q: I live in a small village. In my village there are two masjids, one belongs to Ahal Hadeees, who follow Imaam Shaafi and the other belongs to Hanafi's (who follow Imaam Abu Hanifah).

When azaan starts in one masjid, the other will be starting prayers as they have completed azaan few minutes early. So in this system of prayers, the one azaan in any of two mosque is not given the heed that we are supposed to. So I would like to hear from you, is it wrong or not.

Feeling lust after unintentionally looking at one's sons private part

Q: If a woman unintentionally (accidentally) looks at the private part of her adult son without clothes by mistake and she lowers her gaze, but due to looking at the private part without clothes she feels lust inside and she feels some discharge coming out of her private part. Even though she does not have any lust for her son and she lowered her gaze as well, will it constitute hurmat musaharat?

Giving food away that one would not eat oneself

Q: I am a student who went home for lockdown. My electricity had tripped approximately 15 hours prior to my return. My freezer stuff was not frozen, however it was room temperature and I now have doubts whether I can give it away to someone else as I am not sure if its okay for consumption. I know it is sinful and wasteful to throw away food and it is also sinful to give away food that you would not eat yourself. What do I do?
