*It is lawful for one to greet a group of people among who may be some non-Muslims, but his intention should be to greet the Muslims.
*One should not greet another by simply waving or pointing. Jabir () narrated:
'Do not greet one another with the greeting of the Jews; for their greeting is by shaking the head and waving the hand.'(An-Nasa’ee) *It is lawful for one to greet one who is praying. The praying person should respond with a hand motion. There is no specific method in doing this, for the Prophet () would greet at times using his hand and at others with his head. What is authentically reported is that he would greet by waving his hand.31
