The Prophet (peace and blessings be upon him) said: "None of you truly believes until his desires follow what I have brought." Does this include a man's desire to look at women?

Question:
May Allah reward you, Honorable Shaykh. A questioner says regarding the saying of the Prophet : It is known, Honorable Shaykh, that a person's desires are contrary to what the Messenger of Allah (peace and blessings be upon him) brought, such as a person's desire to look at women or look at what is forbidden. How do we reconcile this with this hadith?

Answer:
Yes, this constitutes a contradiction, and contradictions have degrees. If he looks at women, he has followed his desire. But the meaning of "he does not believe" refers to complete faith; he does not possess complete faith. So this is a sin that diminishes his faith. Yes, it is a negation of the perfection of faith. The glance and other minor sins are a negation of perfection, as are the major sins that are less than shirk (associating partners with Allah). This is a negation of the perfection of faith. As for shirk and major kufr (disbelief), that is a negation of the foundation of faith. Yes.
