When is the index finger raised in the tashahhud, and what is the ruling on moving it?

The questioner:
Yes, who is with us? From Madinah, Basim, go ahead, my brother Basim. Peace be upon you.

The Shaykh:
And upon you be peace.

The questioner:
How are you, Shaykh Salih?

The Shaykh:
May Allah greet you.

The questioner:
If you please, Shaykh, what is the method for raising the index finger in prayer?

The Shaykh:
Yes, the index finger in prayer is raised at the mention of the Name of Allah, or during supplication, raised as a sign of tawhid (the oneness of Allah). Yes.

The questioner:
Some people extend the index finger and it moves until the end of the prayer?

The Shaykh:
Yes, because there is a report or something similar to that that he moves it and that it is severe upon Satan, but the stronger position, and Allah knows best, is that he does not move it; he raises it and does not move it, as a sign of tawhid (the oneness of Allah). Yes.
