Q: Nabi (sallallahu alaihi wasallam) instructed us Muslims to give salaams to those whom we know and those whom we don't know (among the Muslims). How will we know the individuals we are giving salaam to are Muslims or not since we don't know them? Do we just assume that they are Muslims by looking at their clothing, their professions (halaal butcher) or any signs that would be hint of their faith or do we just ask them before giving them salaam?

Q: I teach reverts and very often when we teach them the hadith on salaam they tell us that they very so often don't receive replies to their salaam from our Indian Muslims.
