What is the ruling on frequently looking at women despite trying to overcome that through fasting?

In summary: It is recommended to fear Allah and hasten to marry for those who are able, for it is more lowering to the gaze and more safeguarding of the private parts. And for those who are not able, they should fast, as it is a shield for them. One must beware of forbidden glances, for they are arrows from Shaytan, and a Muslim must lower their gaze and guard their private parts. Through patience and striving against the self, a Muslim attains reward, for the patient will be given their reward without account, and those who strive in Allah's cause, He will guide them to His paths.
