The criterion for the start of travel for shortening and combining prayers when going to the airport

The questioner:
Please, Shaykh. Shaykh, may Allah reward you with good. The criterion is the time of travel; the criterion is the time of travel. For example, I am from Riyadh and I set out for the airport. The time for the midday prayer entered while I was at the airport. Do I start combining and shortening, or not?

The Shaykh:
This depends on the airports. If the airport is inside the town, you have not yet traveled because you are inside the town, and travel does not begin until you leave the town. But if the airport is outside the town, you have begun your travel. So if the time for prayer comes upon you, you shorten and combine. But if the airport is inside the town, you have not yet traveled, so you complete the prayer and do not combine. Yes.

The questioner:
There is no specific limit in kilometers, for example.

The Shaykh:
Up to the limit of the buildings, the last building of the town. If you leave the last building of the town, you have traveled. If you are inside the buildings, you have not left, so you have not traveled.

The questioner:
I mean, the Riyadh airport now is inside the town, for example, close enough that you can see the buildings.

The Shaykh:
It is not a matter of whether you can see the buildings; the matter is whether you are inside the buildings or outside them. The Riyadh airport appears to me to be outside the buildings, not inside them; it is outside. And if you can see the buildings, even if you are in the shadow of the wall, you are outside the town, so you have traveled. Yes.
