Question:
He says: Honorable Shaykh, may Allah grant you success. A man prayed on the day of the festival with the intention of the funeral prayer. When it became clear to him that it was the festival prayer, he changed his intention during the prayer. Does that suffice for him?
Answer:
Or he prays with the imam. Whoever did not pray with the imam, his intention is the imam's intention. And praise be to Allah. Yes.
