Question
If it becomes clear to people after a period of time that the Sheikh they were praying behind was not a Muslim, but a man who hides his disbelief, what should they do? Is it obligatory for them to make up their prayers?
Answer
I say, and with God's help: This is a controversial issue, so it is not necessary to repeat the prayer for those who follow, as long as there is a legal school that states the prayer is valid; otherwise, they must repeat it, and God knows best.
