If one travels after the time of the current prayer has entered, does he pray it shortened while traveling?

Question:
The second question: When traveling, the time for the 'Isha' prayer has entered, or the adhan for 'Isha' has been called, and I am traveling. Is it permissible for me to pray inside the city, or should I wait until I go out beyond the buildings so that I can combine the Maghrib and 'Isha' prayers? I am the mu'adhdhin, and I am inside the city. He says: If you are in the state of travel and the time for the 'Isha' prayer has entered, do I pray it, or do I pray it in the town I arrive at with two rak'ahs?

Answer:
If the mu'adhdhin calls the adhan and you are in the town and have not yet traveled, or you are in your house, then you pray the current prayer in its time, or with the congregation, and then you travel, because you are still a resident. You do not delay the prayer until you leave the town and shorten it. This is not permissible, because it became obligatory upon you in full in the town. Even if you pray it outside the town, you are required to complete it.
