The ruling on raising the index finger during the tashahhud and between the two prostrations

Question:
The questioner says: Honorable Shaykh, when does one raise the finger during the two testifications in the prayer? And do I raise them between the two prostrations as well? I have heard that I should raise it while saying “O Allah,” is this correct?

Answer:
What has been reported is that the index finger is raised at the mention of the Name of Allah as a sign of tawhid (the oneness of Allah). This is done in the first tashahhud and the second tashahhud when one says, “I bear witness that there is no god but Allah,” by raising the index finger as a sign of tawhid. This is a recommended practice (sunnah). As for raising the finger between the two prostrations, meaning in the sitting between the two prostrations, nothing has been reported regarding this. Yes.
