The meaning of marital relations [nikah] is the contract, consisting of what is ordained and sanctioned, its basis being legitimization, and for this reason a pledge is not carried out for it even though it may be deemed desirable. And it may extend beyond permissibility to the rest of the rulings. Its benefit is the preservation of progeny, the releasing of what might cause harm by being retained, and the attainment of delight and enjoyment. And this, namely the attainment of delight with enjoyment, is what is in Jannah, there being no procreation there nor retention. And what is said – if a man desires a child there, he will have the child in Jannah, and the pregnancy, suckling, and weaning will occur in one hour, even if he had no children in this world, like eunuchs or those who are deformed and not intact. And there they will have whatever they desire, even if it was forbidden in this world, like silk, fermented drink, and getting together with two sisters; indeed Al-Qurtubi clarified that it is permissible to have marital relations with any unmarriageable relatives [maharim] in Jannah – except with a mother or daughter – because the reason here is mutual hatred and the severing of kinship ties, but this no longer exists there, as opposed to depravities like intercourse in the rear or intercourse among each other like with one’s daughter or mother. It is narrated: In Jannah each of you will be given a penis like a lofty palm tree and a vagina to accommodate it.
