The Messenger of Allah صلى الله عليه وسلم said: “O you youngsters. Whoever amongst you who can afford to marry should marry, because it will help him more to lower his gaze, and guard his modesty (i.e. private parts from unlawful sex). And whoever is not able to marry he should fast, because it will be protection for him.”
