Is masturbation permissible while imagining a foreign woman or an imaginary woman, knowing that refraining from it causes psychological and physical distress, and that this matter results from a medication used to treat a benign tumor that cannot be stopped?

We ask God to heal you and enrich you. We have previously explained the prohibition of masturbation and its harms. If many scholars forbid imagining a foreign woman while a man is having intercourse with his wife, then doing so with masturbation is even more forbidden. We advise you to fear God Almighty and to marry a second wife if you can, to protect yourself from what is unlawful.
