ツ smiling at your brother is an act of charity ツ Prophet (pbuh) had told us that your smiling at your brother is an act of charity. Nowadays, people accuse practicing Muslims of being rude and frowning all the time. If you are truly a practicing Muslim, you must change & wear a smile on your face. Your smile is your way to people’s hearts. This is of course to the same sex. It is not permissible for a brother to go around spreading his smiles to the sisters or vice versa!
