The ruling on Kissing the Hand and Putting it on the Chest
Question:
As some people greet each other, I notice that they kiss the other persons hand or place them on their chest, seeking, I assume, to increase the mutual love they have for each other. Is this permitted in Islam?
Answer:
This action has no origin in the Islamic Shariah. It is not legislated to kiss the hand or place it on the chest after shaking, rather it is an innovation when the one doing it thinks that he is drawing closer to Allaah Almighty by doing it.
