It is stated from Imam Ja'far-e-Sadiq (a.s.) that one should not salute three types of persons: a) A person who is walking alongwith the janaza b) A person who is going for Namaz-e-Jumma (Friday prayers) c) A person who is in the bathroom and perhaps has no cloth wrapped around him According to Imam Mohammed Baqir (a.s.), if a person reaches the mosque when everybody is busy with prayers then he should not salute (say salam) to those who are busy in prayers, instead he should take the name of the Holy Prophet (s.a.w.a.) and join the prayers concentrating on them.

But if you reach a gathering where people are talking among themselves, then you should surely perform the salutations.

According to Hazrat Ali (a.s.), when one enters one's house, one should say salams to all those present in the house but wheen the house is empty, one should say: ‘May peace be on us from our Creator.’ According to the Holy Prophet (s.a.w.a.), when you meet each other, you should say salams and shake hands and when you part with each other then you should pray for each other's salvation.

According to another tradition, a person who, on reaching his home, performs salams to the members of his family (wife and children), God will bless his house and the angels will cultivate an association and affection with it.

Etiquette of shaking hands, touching necks (embracing) and kissing: According to Imam Ja'far-e-Sadiq (a.s.), the salutation is complete when people shake hands after saluting each other provided they are living in the same city; but if a person has returned from a journey then his salutation is only complete after embracing. A reliable tradition from Hazrat Abu Obeida states that he was sitting in the same kajawa with Imam Mohammed Baqir (a.s.) while once travelling together.

While boarding the kajawa Abu Obeida used to sit inside first and then the Imam (a.s.) used to follow and when both had seated themselves comfortable in the kajawa, then the Imam (a.s.) used to salute him and ask about his welfare as though he had met him after a long time. And when it was time for alighting, then the Imam (a.s.) used to step down first and Abu Obeida used to follow.

And when both reached the ground safely, then the Imam (a.s.) used to salute Abu Obeida and ask of his welfare in the same manner.
