What is the ruling on finger snapping and interlacing the fingers?

The Shaykh : As for finger snapping and interlacing the fingers, there is no harm in them except during prayer, during prayer; because clicking the fingers is not compatible with the stillness required in prayer. As for interlacing the fingers in prayer, the prohibition has come regarding it, and indeed the prohibition has come regarding interlacing the fingers while you are turning toward prayer or while you are waiting for prayer. So in prayer, interlacing the fingers is not permissible, a fortiori.

The questioner : ... This finger snapping makes a sound with the fingers ... .

The Shaykh : What do you mean?

The questioner : That is: by raising [the hand] with the snapping.

The Shaykh : Finger snapping with the fingers, what is meant by it?

Another questioner : With a sound.

The Shaykh : ... With a sound, why is this done?

Another questioner : During dancing, it is a type of dancing.

The Shaykh : Who is the questioner? Let him clarify to us what he means by his question?
Yes.

Another questioner : To draw attention ... so that people notice ... so he snaps, meaning.

The Shaykh : Yes, to draw attention. Do you see where the questioner is and where you are? This is our problem. He says: to draw attention; to make a sound, meaning. I do not see anything wrong with it.
