How can one deal with people who express a desire to masturbate, and how can they be invited to God, especially when the young man himself fears temptation?

Allah does not look at your images or your wealth, but He looks at your hearts and your deeds. Mixing with women is not permitted except with adherence to Sharia guidelines, such as lowering the gaze, avoiding seclusion (khalwa), and refraining from handshakes. One must also beware of mixing with men of weak faith or those lacking chivalry, avoid seclusion with them, and ensure that speech is serious, avoiding softness or flirtatiousness when addressing men, and refraining from wearing tight clothes. Adherence to the obligatory etiquettes of Islam, such as growing a beard, is also necessary. It is recommended to fear Allah, seek His help, and ask Him to remove affliction. If you are afflicted by someone who has no share [in the Hereafter], then keep them away, speak sternly to them, and warn them of Allah.
