Shortening the Prayer in a Short Journey

Question:
Another questioner asks, saying: Abdullah ibn 'Umar said, "If I travel a mile, I shorten the prayer," following the example of this Companion. I travel from Riyadh to Diriyah, so I shortened the 'Isha' prayer in my prayer. Is my prayer valid or not?

Answer:
This is a mistake. This is not travel. Travel is not considered travel unless it requires provisions and extra supplies. The scholars defined it as two days of intended travel, meaning two stages, meaning four farsakh. As for Diriyah now and Riyadh, they are one thing. Diriyah is travel, but Diriyah has connected with Riyadh and become one place. So the one who intends to travel between Diriyah and Riyadh is mistaken. He must repeat the prayer as four rak'ahs. One does not combine prayers except in a place that is considered travel, meaning a distance that people consider a distance, that they consider travel, where the traveler needs to carry provisions and water with him, because it is travel. The common distance is seventy or eighty kilometers. This is the common case. Yes.
