77.Female circumcision:

“…That is because the purpose of circumcising a man is to make him clean from the impurity that may collect beneath the foreskin. But the purpose of circumcising women is to regulate their desire, because if a woman is not circumcised her desire will be strong. Hence the words “O son of an uncircumcised woman” are used as an insult, because the uncircumcised woman has strong desire. Hence immoral actions are more commong among the women of the Tatars and the Franks, that are not found among the Muslim women…” Majmoo’ al-Fataawa, 21/114 https://islamqa.info/en/9412

Therefore the male circumcision is obligatory and female circumcision is Sunnah.

78.What should a Muslim do if he gets horny?

Recommendation to the one who sees a woman sexually aroused is to go to his wife or slave woman and have intercourse with her.

Jabir reported that Allah's Messenger (ﷺ) saw a woman, and so he came to his wife, Zainab, as she was tanning a leather and had sexual intercourse with her. He then went to his Companions and told them: “The woman advances and retires in the shape of a devil, so when one of you sees a woman, he should come to his wife, for that will repel what he feels in his heart.( Sahih Muslim 1403a, Bk.16, H.10).

Lusting after other women is the breaking of the 9^th commandment for a Christian or a Jew (Dt.5:21)

79.Sexual Abstinence is forbidden in Islam:

The wife of Uthman came and she said: O Messenger of Allah ‘Uthman is fasting all day long and praying all night long, therefore the prophet went out and was angry carrying his shoe (with his hands) and he came to ‘Uthman where he found him praying and he said: “Allah never sent me to be a monk but he sent me to be Hanif (a name of the group claimed to be the followers of Abraham), I fast and pray and I do have intercourse with my women so who ever accept my lifestyle he should follow the same, and my lifestyle… Al-Kafi V 5/11 496 – Wasil Al-Shi’a 25157, as quoted by Christian Prince, Sex & Allah, Vol.1, page 99.

80.No sex during menstruation. But Muhammad exempted from it.

Maimunah daughter of Al Harith said “When the Apostle of Allaah(ﷺ) intended to associate and lie with any of his wives who was menstruating, he ordered her to wrap up the lower garment(loin-cloth) and then he had association with her. (Sahih, Sunan Abi Dawud 2167, Bk.12, H. 122).

Because he knew this revelation was not from Allah but was his own.  If it were really from Allah how would he dare to do it when he had other wives who did not have menstruation that day.

81.Necrophilia? Sleeping with a naked dead body in the grave:

“When Fatima Binte Asa, mother of ‘Ali died. At the time of her burial, the Messenger Allah took off his shirt dressed Fatima (the dead women)[sic]in it. Then the Holy prophet himself lay in that grave with her. And after they buried her, people questioned about the reason of doing so (lay in that grave with her), they said prophet of Allah you did something nobody did ever before! The Holy Prophet replied: I dressed her with shirt so she will wear clothing of heaven and I slept with her in her grave to dismantle the pressure of her grave, she was one of the best women [sic] for me” Majm’a Al-Zaw’ed hadith 15400/ Ma’refat Al-Sahaba hadith 273 book of Kaniz Al-‘Umal 37609 (as quoted by Christian Prince, Sex and Allah, Vol.1, page 83).

It is assumed that he was having sex with her in her grave. If not, then, what is the logic behind what he did there? Even if one may say he did it for the forgiveness and mercy! When a prophet does a thing like that, will Allah remove the punishment of the grave for? She was not a Muslim while she lived. And the Quran affirms that no matter what, even when Muhammad begs for Mercy for a non-Muslim Allah will not grant it (Q.63:6). Therefore,  it affirms that Muhammad had  mental sickness of necrophilia. Muhammad is the pattern of behavior for other Muslims. And if he did it to help her get the mantle of heaven by his wearing her his shirt, then other Muslims should also practice it.
