Always remember that a good and trustworthy Muslim man is the one who would treat girls around him exactly the way he wants his sister to be treated by other men (non mahram).
If he wants his sister to be respected by other men, he would treat girls around him with respect.
If he doesn't want that his sister be hurt or brokenhearted by any man, he wouldn't hurt or break the heart of any girl he meets.
If he doesn’t allow his sister to have a boyfriend, he wouldn’t let himself have a girl friend.
If he doesn’t allow his sister to have male friends he wouldn’t let himself have any female friends!
Muslim men like that are few, but they exist alhamdulillah. ♥
May Allah guide us and all our brothers in Islam to the right path.
Ameen ya Robb.
