Offering the prayer before the funeral prayer or the obligatory prayer for one who enters the mosque

Question:
A man says: He entered the mosque and found them praying over a funeral. Should he pray the obligatory prayer, or should he pray over the funeral first and then pray with them?

Answer:
If he enters while they are praying over the funeral, or if the funeral is about to be brought in, he should pray over the funeral first; because it is something that is missed, whereas the prayer is not missed. He prays over the funeral, then prays the obligatory prayer that he missed. He starts with the funeral. Yes.
