What is the ruling on the lesson after the four rak'ahs in the Tarawih prayer?

There is no harm in having a lesson between the rak'ahs of Tarawih, but it is preferable not to make it a regular practice, so that people do not come to believe it is part of the prayer or obligatory. The Imam can alert people to the rulings of Sharia, especially what they need during Ramadan. These words are more beneficial than leaving or engaging in worldly talk, and better than innovated dhikr. Some scholars have opined that there is no need for a break between the rak'ahs in this era due to the brevity of the prayer, but if it occurs, it is better to utilize it for advice, remembrance, or beneficial reading.
