{ And share with them in wealth and children } Al-israa 64

Regarding His word { And children } … in some of the narrations of Ibn ‘Abbas it is related that a man came to him and said: My woman awoke like there was a flame of fire in her vagina. He said: That is from the genies [jinn] having intercourse. The man said: And who are their children? He said: Those are the effeminate ones.
Ja’far ibn Muhammad related: Indeed Satan sits on a man’s penis, and whenever he does not invoke Allah [i.e. say Bismillah], he comes upon the man's woman with him, and he ejaculates in her vagina just like the man ejaculates.
