What is the ruling regarding the days a young man intentionally broke his fast during Ramadan as a result of watching unlawful things?

You must take the initiative to repent to Allah Almighty for the forbidden acts you have committed, by abandoning the sin, regretting it, and resolving not to return to it. If you broke your fast in Ramadan due to eating, drinking, or masturbation, or if semen was discharged due to watching forbidden scenes, you must make up for the days you missed. Allah accepts repentance, forgives sins, and loves those who repent. Repentance is accepted even if the sin is repeated. Part of sincere repentance is avoiding the causes of disobedience and cutting off the paths leading to it. If you are able to marry, then hasten to do so; otherwise, practice chastity and be patient. Seek help from Allah, occupy your time with what benefits you, associate with the righteous, and maintain physical exercise.
