This is one of the steps of satan! In few weeks, looking at such stills or clips where women are there and uncovered would be normal for you!

You must lower your gaze from looking at non mahram women or anything haram.

Sheikh, recently, I’ve started watching health & fitness videos of Dr. , an American doctor. His videos are truly helpful & informative. Only problem is sometimes, not regularly, still images or 3 to 4 seconds length videos of women pop up. Again, the content of those videos are really helpful. Am I sinful if I keep watching those videos?
