The ruling on one who prays in a direction other than the qiblah after asking?

Question:
He says: Honorable Shaykh, may Allah grant you success. We traveled to one of the Arab countries, and when the time for Maghrib arrived, we intended to combine it with 'Isha'. So we asked about the qiblah, and one of the residents directed us to a specific direction, so we prayed Maghrib. And when we wanted to pray 'Isha, a man from the people of this country came to us and directed us to the opposite direction, so we repeated Maghrib and then prayed 'Isha. Is what we did correct, or was the Maghrib prayer valid?

Answer:
The Maghrib prayer is not valid, because as long as you are in a Muslim country where there are mosques, and you see the mihrabs, you see the mihrabs in the mosques, and you pray in the direction of the mihrab in the mosque, then you are not excused, and you do not suffice with the statement of the informant, and you have mosques. Yes.
