Entering with the imam while the imam is in tarawih, does one get the reward?

The questioner : He prayed. He entered with the imam while the imam was in tarawih. And he entered with him in tarawih.

The Shaykh : Yes, but it is not like the reward of the first congregation.

The questioner : Imam Ahmad explicitly stated that one should pray before praying the Qira'iyah, and the school of thought says that it is obligatory that one not pray before praying the Qira'iyah.

The Shaykh : Yes, because the school of thought has two types: a personal school and a conventional school. What is in the books of the later scholars is a conventional school. Sometimes Imam Ahmad’s explicit statement is contrary to this, whether in acts of worship or in transactions. Yes.
