The ruling on interlacing the fingers while waiting for the prayer

Question:
May Allah reward you, Honorable Shaykh. He says: If a Muslim prays and then sits waiting for another prayer, is there any blame on him for interlacing his fingers, or is this specific to the time between the adhan and the iqamah?

Answer:
No, this applies to everyone who is waiting for the prayer: he does not interlace his fingers. If he is on his way with his heart focused, he does not interlace his fingers. If he is sitting in the mosque waiting for the iqamah, he does not interlace his fingers. However, if he is close to the prayer and it has ended, there is no harm in interlacing his fingers, as the Prophet (peace and blessings be upon him) did.
