Does the ma'mum stand to complete his prayer after the imam's first taslim or the second?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: When does the ma'mum separate from the imam if he wants to stand up? Is it after the imam's first taslim or after the second taslim?

Answer:
The second, the second. He does not stand up until the imam has said the second taslim, because he does not know whether something of the prayer might remain, such as sujud al-sahw or something else. So he should not rush until the imam has said the second taslim. In fact, the jurists said that if he stands up after the first taslim, his prayer becomes a nafilah (voluntary prayer). So he should be cautious of this. Yes.
