Explanation & Benefits
Shaykh Maulana Usman Muneeb
Benefits and Issues: The complete form of greeting (salam) is the handshake (musafahah), through which the sins of those who shake hands are shed. Sayyiduna Anas radi Allahu anhu, in order to further enhance this, would apply fragrance to his hand so that his Muslim brother would feel happiness.
