We entered to pray and found the second congregation to be of young age, with their imam being 11 years old, so we formed another congregation.

Question:
He says: Honorable Shaykh, may Allah grant you success. We entered the mosque as a group and saw a group of young boys praying Maghrib, and their imam was approximately eleven years old. So we did not pray behind them because we saw that they were young, and we prayed in another congregation. Is what we did correct?

Answer:
What you did is correct, but it is better that you had joined those who were praying, as long as their imam is of discernment and recites well. It is better that you had joined him. Yes.
