Is it valid to combine the Zuhr and 'Asr prayers for one who arrives before the 'Asr adhan?

Question:
Honorable Shaykh, may Allah grant you success. A questioner says: I am a teacher outside the city of Riyadh, at a distance that qualifies for shortening the prayer. When I leave the school, I combine the Zuhr and 'Asr prayers. Then I arrive in Riyadh before the 'Asr adhan every day, so I sleep and do not wake up until Maghrib. Is my combining of the 'Asr prayer with the Zuhr valid, given that I arrive before the 'Asr adhan every day?

Answer:
Yes, your combining is valid, if Allah wills, and it is more convenient for you. Yes.
