Ruling on combining prayers by advancing them for a traveler on the road

Question:
This is 'Azam from Makkah al-Mukarramah. He says: These are my questions, may Allah reward you, Shaykh Salih. If I am traveling from al-Ta'if to Makkah and the time for the midday prayer (Zuhr) catches me on the road immediately after I have left al-Ta'if, may I combine and shorten the midday and afternoon prayers (Zuhr and 'Asr), even if I will arrive in Makkah before the time for the afternoon prayer?

Answer:
Yes, if the time for prayer enters after you have left your town as a traveler, you may combine the two prayers and proceed on the road, even if you will arrive at the town you are heading to during the time of the second prayer, the time of the second prayer. It is permissible to combine by advancing them, even if you will arrive at the town during the time of the second prayer. This is regarding permissibility. As for what is better and more preferable, it is that you pray the midday prayer shortened on the road, and you pray the afternoon prayer when you arrive, exactly in its time.
