When is a traveler permitted to shorten prayers if they travel and return on the same day to their original place of residence within the same country?

It is permissible for a traveler to shorten the four-rak'ah prayers if their journey is lawful and they have covered the distance of qasr (shortening prayers) after leaving the urban area, which is approximately 83 kilometers, either one-way or round-trip. The method of shortening is to perform the four-rak'ah prayers (Dhuhr, Asr, and Isha) as only two rak'ahs.
