When is it prescribed to sit in the turuk position, and when does one sin by doing so?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, the turuk position is a recommended practice (sunnah). So when is it prescribed? And when does one sin by doing it? And what are the limits of causing harm with it?

The Shaykh:
The sin is in doing it because it is among the prescribed acts in prayer, but it is the turuk position. He says the turuk position is

The questioner:
Yes, Shaykh.

The Shaykh:
The turuk position is only in the prayer that has two sittings: the first tashahhud and the second tashahhud. The turuk position is in the second tashahhud. The first tashahhud is done in the iftirash position. As for the prayer that has only one sitting, like the Fajr prayer, this is a point of disagreement among the scholars. The stronger position, and Allah knows best, is that one does not sit in the turuk position in it, but rather sits in the iftirash position. Yes.

The questioner:
And if he causes harm to his neighbors by doing so, does he sin?

The Shaykh:
No, he does not bother the neighbors. No, he does not bother the neighbors. If sitting in the turuk position in the final tashahhud bothers the neighbors, no, he sits in the iftirash position. Yes.
