Then Abu Obeida said, "O son of the Holy Prophet (s.a.w.a.) none of the people around us say and do what you say and do." Then the Imam (a.s.) replied that perhaps Abu Obeida was unaware of the rewards of salutation and hand-shaking; as long as two momins are busy in saluting each other and shaking hands, their sins are falling away from them as leaves from trees and as long as these two are in each other's company, God is blessing them with his kindness and mercy.
According to Imam Ja'far-e-Sadiq (a.s.), whenever the Holy Prophet (s.a.w.a.) used to shake hands, he never used to withdraw his hand unless the other person returned it first. In another tradition he has stated that one should shake hands as shaking hands lessens rift.
Gathering and etiquette of sitting in the gatherings: It is stated that the Holy Prophet (s.a.w.a.) had willed unto Hazrat Ali (a.s.) that if eight types of persons are insulted, then they should curse themselves: a) A person who is an un-invited guest at a party b) A person who dominates over the Lord of the house c) A person who expects kindness from his enemies d) A person who expects to be obliged by the stingy and mean people e) A person who interferes when two persons are talking without permission f) A person who is scared of the king g) A person who sits at a place in the gathering which is below his dignity h) A person who is talking to another person who is not hearing his talk According to Hazrat Ali (a.s.), a person who sits at the head of gathering without possessing these qualities is a fool: a) Whatever question is put to him, he should be able to answer b) When other people are fed up of talking about justice, he should be able to clarify the complete picture c) He should advise in such a manner that people are benefitted by following that advice According to Imam Ja'far-e-Sadiq (a.s.), when a group is sitting in a gathering then a momin should sit behind it as jumping over the heads of the squatters to reach the celebrity of the gathering is lack of manners.
In another tradition he has stated that in a large gathering someone has taken your place and other people are making place for you, then you should accept their hospitality and sit, as it is a sign of respect shown to you by a brother momin. If there is no place left and no one is making place for you, then you should sit where ever it is possible.
