I prayed on the bus out of necessity before the time ended, not facing the qiblah, with the qiblah behind me!

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: I traveled from Makkah to Riyadh on a Friday at two in the afternoon, and the bus did not stop, so I was forced to pray the 'Asr prayer on the seat half an hour before the Maghrib adhan. My direction was toward Riyadh, and the qiblah was behind me. Is my prayer valid?
Answer:
What prevents you from facing the qiblah in the car? You turn around in the car, on your seat, and stand to pray toward the qiblah. You must repeat the prayer, meaning you have no excuse for leaving the qiblah. Yes.
