The sunnah is to greet the muslims with salam – assalamu alaikum – when meeting them and when parting with them. However, whatever you have mentioned is permissible to be said.

If we r in any conversation whether its in phone or face to face, end of our conversation we usually say goodbye or allah hafiz, or fi amanillah or ma’assalama. What is the best to use ? Or what is sunnah?
