Question:
Honorable Shaykh, the questioner says: A person caught up the second rak'ah of the 'Isha prayer in this mosque and intended it as Maghrib. In this case, he did not sit for the first tashahhud. What should he do? And if he performs the tashahhud with a light sitting, is there anything required of him?
Answer:
No, he does not sit, as that would contradict the imam. He follows the imam, and the first tashahhud is dropped from him; the imam bears it for him. Yes.
