Question:
Honorable Shaykh, may Allah grant you success, the questioner says: You mentioned, may Allah preserve you, a moment ago that it is not permissible for two congregations to pray at the same time. However, some people enter the mosque and see small children praying in congregation, so they do not pray with them, but rather establish another congregation. What is the ruling on his action? And is this considered arrogance?
Answer:
If the children are adults, their prayer is valid, so he joins them. If the children are of discerning age but not adults, if they are of discerning age, their prayer is valid, so let him join them and not pray alone. Yes. And if a group comes to pray with the children, there is no obstacle, because their prayer is valid, and praise be to Allah. Yes.
