The ruling on moving the index finger during the tashahhud

Question:
What is the ruling on moving the index finger from the beginning to the end of the tashahhud?

Answer:
Raising the index finger during the tashahhud and during supplication is a recommended practice (mustahabb), as it is a sign of the oneness of Allah (tawhid). As for moving it, there is scholarly disagreement (khilaf) among the scholars. Whether one moves it or not, there is no harm in that. Yes.
