Q: When a non-Mahram comes to my house accompanied by a Mahram, I shouldn’t go and greet them right? Like two of my female cousins and my aunt. I shouldn’t go to greet them, correct? Especially if one doesn’t follow Islamic etiquette?
A: It is not advisable to become informal and casual. If you have to, then greet them from a distance.
And Allah Ta’ala (الله تعالى) knows best.
