What is the way to get rid of masturbation, which is practiced by a 17-year-old young man, especially with his feeling of distress and desire to sleep, which ends in practicing it after a period of abstinence?

The optimal solution for abandoning a bad habit is marriage. If marriage is not possible, then chastity (abstinence) should be observed, in compliance with the words of Allah Almighty: "And let those who find not the financial means for marriage keep themselves chaste, until Allah enriches them out of His Bounty." One must continue to strive against the self and repel thoughts and ideas before they transform into desires and actions, and then into habits difficult to abandon, as mentioned by Ibn Al-Qayyim. If one falls into sin, one must hasten to seek forgiveness, renew repentance, and perform good deeds, in accordance with the words of Allah Almighty: "And those who, when they commit an indecency or wrong themselves, remember Allah and seek forgiveness for their sins," and the words of the Prophet, peace and blessings be upon him: "And follow up a bad deed with a good deed, it will erase it."
