What is the ruling on the process of ejaculation in a clinic to obtain seminal fluid, and what is the ruling on using and displaying pornographic materials (magazines and films) to stimulate the patient to ejaculate seminal fluid in a medical clinic?

Masturbation by any means other than one's wife or what one's right hand possesses is forbidden, based on the Almighty's saying: "And those who guard their private parts, except from their wives or those their right hands possess, for indeed, they are not to be blamed. But whoever seeks beyond that, then those are the transgressors." It is not permissible to look at indecent pictures due to the temptation and falling into indecency that results from it.

If your friend is married, let him masturbate with his wife's hand, then bring the fluid at a time when it remains viable for analysis. If he is not married, let him wait until he gets married, then masturbate with his wife's hand at that time.
