IF a boy loved a girl and used to look at her, and then repented from that. But after that he saw some dream which saddens him, and the girl lives near his house. But the boy now lowers his gaze and does not look at the girl. But his heart is burning and he cannot forget the girl. Can you give some ways to remove the love of this girl and forget her ? Please give some effective means.
He should fear Allah and should remind himself that all this is not allowed in Islam and be grateful that he was guided before falling into more sins. If he is mature enough, he should talk to his parents about marrying that girl if she is a practicing Muslim. If he is unable to do that, he must fast in order to block such thoughts and to strengthen his Iman as Satan is targeting it big time.
