In this respect...
In this respect, a well-known Chinese proverb says: "The one who does not know smiling well, should not open a shop." because smiling is a successful seller. 2- Handshaking: It is a great hearty expression of love of the hand giver to the hand receiver; indeed, it is a general language of love and kindness that doesn't need a translator. Whenever you put your hand into the hand of your friend, both of you will feel the sense of love and affection for each other.
It was reported in a narration encouraging handshaking to the extent that whenever two people shake hands their sins will fall away the way the dried leaves of a tree fall. Imam Muhammad al-Baqir (a.s.) said: "When two people meet and shake hands, Allah will turn to them, and their sins will fall as the leaves of the tree fall." 3- Greetings: Greetings between people is an expression of love and affection. But, the Islamic greeting "Assalamu Alaikum" (i.e.
peace be upon you) is full of greater expression than the one mentioned above. It is an expression of peace, which the whole world is looking for. From this, we can understand what was reported in a narration. "The Almighty Allah likes he who starts greeting." Whenever you extend your greetings to whomever you meet, whether you know him or not, you are extending flowers of love and peace on people's way, as well as, putting peace and tranquility into their hearts.
The great achievement, for a person, is when others feel secure and have peace of mind whenever they meet him. And what a good behavior, when peace is exchanged with peace, while answering greetings in kind with what is better than that. Based on general moral laws, a poet has said: "In every hour of the day You can give something as a gift. It might be smiling, And it might be extending hands in hand shaking.
And it might be a word; Through which you strengthen others' determinations." 4- Embracing: If smiling is a key to a bright meeting and greetings are a source of tranquility and handshaking is a greeting from a heart to another heart, then embracing is a source of expressing what smiling, greetings and hand shaking were unable to express. The Holy Prophet (s.a.w.) is reported to have embraced Ja'far al-Tayyar and kissed his face.
