Is it permissible for a traveler to combine and shorten prayers (Dhuhr with Asr, and Maghrib with Isha) at any time between them, or to delay them until after the time of the second prayer? And must the prayer that was combined and shortened be repeated if the traveler arrives in Jubail before the time of the second prayer begins?

The majority of jurists hold that the travel for which concessions are legislated is what is conventionally considered travel, approximating a distance of eighty kilometers. You are permitted to shorten and combine prayers.

Prayer in Dammam: You may shorten the Dhuhr, Asr, and Isha prayers if you pray individually or with a group of travelers. However, congregational prayer is obligatory for an able man. If you hear the call to prayer, you must attend the congregation and pray in full if the imam is a resident. Combining Prayers: Combining prayers is permissible in Dammam. It is preferable not to combine them unless performing each prayer at its appointed time becomes difficult. You may combine prayers by offering the earlier prayer with the later one (gathering of advancement) or the later prayer with the earlier one (gathering of delay). Prayer Times: The time for Asr extends until the sun turns yellow, and for Isha until midnight. Combining with Delay (Jam' Ta'kheer): If you combine Dhuhr and Asr with delay, it must be before the sun turns yellow. If you combine Maghrib and Isha with delay, it must be before midnight. Returning Before the Time of the Second Prayer: If you combined prayers by advancement and returned before the time of the second prayer began, you are not obligated to repeat it. However, it is better not to combine unless there is hardship. Combining on the Road: In the case of combining with delay, it is permissible to perform the prayer in an area near Jubail before entering the city's built-up area. Arriving Without Praying: If a traveler arrives without having prayed, then if he arrives within the time of the first prayer, he prays the first in full, then the second in full. If he arrives within the time of the second prayer, he prays the first shortened, then the second in full. Praying Behind a Resident Imam: A traveler is obligated to attend the congregation if called to it. If he prays behind a resident imam, he must complete the prayer with four rak'ahs, whether he caught two rak'ahs, more, or less.
