When you go to meet a person do not disturb him by intruding while he is busy. If for example, he is engaged in Tilaawat, Wazeefah or he is in privacy or sleeping or preparing to sleep or involved in something else in which he will be disturbed if you intrude or he may be inconvenienced by your intrusion, then at such a time do not greet or shake hands. Either go away and return later or wait elsewhere (where his attention will not be attracted). If the matter is urgent and requires immediate attention, seek his permission first.
When having arrived at the venue of the person whom you wish to meet, inform him of your presence either by salaam, speech, etc. Do not sit in a concealed place or in such a way that he has not learnt of your presence. Perhaps he wishes to say something which is not intended for your ears. It is evil to listen in to another person's secrets without his consent. If you realize that the discussion in progress is not for your ears, immediately take leave.
When meeting someone with whom you have no informal association, do not ask him about the condition of his home affairs. Similarly, do not ask him about his source of earnings, possessions, etc.
On meeting a person do not linger too long so as to cause him inconvenience or to constitute an impediment in his activity.
When meeting someone, do so pleasantly and smilingly so as to please him.
When meeting someone for the first time, remember the following things:
Introduce yourself State your name.
State your hometown or the country or city from where you are coming.
State the purpose of your visit.
When meeting a person, do not pick up any letter, paper or book from nearby to read.
When someone comes to meet you (and if you are sitting) get up or move slightly. In this is respect for the visitor.
