Dear respected Shaykh, assalamu alaikum wa rahmatullahi wa barakatuh. One of my brothers told me that if he is attracted to a woman, he deliberately imagines himself having sex with her. He said that he did not have sex and he did not speak of his attraction to the concerned women. The hadith concerning this issue is known. Some scholars prohibit this action, but I do not know of their proof. What is your opinion on the actions of this brother? May Allah reward you. يتخيل نفسه يزني فما الحكم
