The ruling on repeating handshakes upon meeting or greeting the worshippers after prayer

The questioner:
May Allah reward you. This is a listener from Algeria who sent a number of questions. In the first one, he says: Is it permissible to shake hands constantly, such as when selecting brothers in the mosque, and then after finishing the prayer, and the like?

The Shaykh:
It is not permissible to repeat the handshake unless a separation has occurred. If they meet and one shakes the other’s hand, then they part ways, and then they meet a second time, there is no harm in shaking hands, or it is recommended. However, if they are all together and have not parted, there is no repeating of the handshake, and there is no need for it. Yes.

The presenter:
We see this scene in the mosques often when the imam finishes his prayer; the middle of the mosque rushes to say, "Peace be upon you, may Allah do you good," and so on.

The Shaykh:
If he did not greet him and did not meet him, there is no harm. But if he had already greeted him and met him, there is no special designation for what comes after the prayer. Yes.
