Ruling on the prayer of one who raises his head from prostration before the imam

Question:
One of the listeners, Muhammad al-Tayyib from Sudan, sent a message containing two questions. In his first question, he says: What is the ruling on the prayer in which I raised my head from prostration before the imam? Please clarify this for us. May Allah reward you with good.

Answer:
If you raised your head before the imam, you must go back and prostrate, then raise your head after him. If you did not do so because you were ignorant, you owe nothing, and the prayer is valid. However, if you knew the ruling of the Shari'ah, you did this intentionally, and you did not go back to prostrate, your prayer is invalid and you must repeat it.
If you were ignorant, the prayer is valid, and you should not return to that practice. If you raise your head thinking the imam has raised his, and then you realize he has not, go back and prostrate, then raise your head after him. Yes.
The presenter: May Allah reward you with good.
