Explaining the distance for shortening the prayer

Question:
The questioner says in this question, O His Eminence the Shaykh, he says: Is it permissible for a person to combine the prayers if he is walking a distance of twenty to twenty-five kilometers while riding a mount?

Answer:
He is not allowed to combine them; rather, it is obligatory for him to pray each prayer in its time, unless he is a traveler. This is not travel. If he is a traveler, he may combine them. As for a distance of twenty kilometers, twenty-five kilometers; this is not travel. Travel is eighty kilometers or more. This is the relied-upon position: eighty kilometers or more, a day and a night for the traveler, meaning a day for the mount, a day and a night for the mount, so its measure is approximately eighty kilometers.
So if it is this distance, or more; he shortens and combines. But if he goes out for a pleasure trip, or for other reasons, like twenty kilometers, thirty kilometers, forty kilometers, fifty kilometers, he does not shorten, and he does not combine. He prays each prayer in its time, and he prays it as four rak'ahs. Yes.
