The ruling on interlacing the fingers while waiting for the prayer and after it

Question:
He says: Honorable Shaykh, may Allah grant you success, is cracking the fingers and interlacing them after the prayer from the practice of the Messenger (peace and blessings be upon him)?

Answer:
Cracking the fingers, no, this is idle behavior. As for interlacing the fingers, it is not permissible. When you come to the prayer, do not interlace your fingers. When you sit waiting for the prayer, do not interlace your fingers. When you are in the prayer, do not interlace them. But after the prayer, there is no harm; the Messenger (peace and blessings be upon him) did it after the prayer. Yes.
