Ruling on shortening the prayer at the boundaries of the town in which one resides

Question:
I was traveling a distance of three hundred and twenty kilometers, and I intended to shorten the prayer, but I did not shorten it until I was close to Riyadh. Is this shortening valid, or do I have to repeat the prayer in full?

Answer:
As long as the traveler has not entered the town, he has the right to shorten the prayer. So if he walks from Makkah to Riyadh and does not shorten until he reaches... and the like... the buildings, there is no harm. Or if he walks from Riyadh to al-Qasim, or to elsewhere, and does not shorten until he has passed most of the road, near the town he intends to reach; there is no harm. But when he reaches its buildings and its houses, no. If it is his home town, and he is heading to his home town, and he reaches its houses, he completes four rak'ahs. Or if it is a town in which he intends to reside, he completes four rak'ahs.
The point is: that during the journey, before reaching the town, he has the right to shorten. The Prophet (peace and blessings be upon him) used to shorten on the road before reaching Madinah (peace and blessings be upon him). And after leaving Madinah, if he intended to travel, he would shorten (peace and blessings be upon him).
