Discussion of supplication during the tashahhud while moving the finger.

The Shaykh : The Prophet (peace and blessings be upon him) ... and he would proceed to the tashahhud ... with his left hand on his left thigh, and his right hand on his right thigh, and he would clench all his fingers, forming a circle with the middle finger and the thumb, and raising the index finger. He said—and this is the point of interest—"I saw him moving it, supplicating with it." So, the movement is linked to the supplication. In the situation you asked about, the follower has finished the supplication ... so the movement ends, because the movement is linked to the supplication. But I remind you why the one praying should not stop the supplication, as it is a place for what he remembers or does not remember of supplications. So, let him continue with the supplication until the imam stands up or until he says the taslim. At that point, there is no need for such a question, because the supplication continues and the movement continues.
