How can fasting benefit young people if they fast and then masturbate after breaking their fast, considering that the Messenger of Allah, may Allah’s prayers and peace be upon him, guided young people to fast?

The Prophet, peace and blessings be upon him, urged those unable to marry to fast in order to reduce desire. The fasting that weakens desire is frequent and extensive fasting, which requires certainty and patience. The effect of fasting may not appear at its beginning. Scholars have mentioned that the reason for the ineffectiveness of fasting for some young people is due to the strength of their desires and the presence of things that strengthen them, such as abundant and varied foods. Whoever wishes to break the intensity of their desires should reduce eating and avoid tempting foods. Similarly, a young man must fast from sins. True fasting is not only abstaining from food and drink, but also lowering the gaze and avoiding places of temptation. One must stay away from masturbation, as it is forbidden and increases desire.
