Whether employees making work rounds are permitted to use concessions of traveling

Q 2: We are employed in a governmental department in the city of Al-Bahah. For work purposes, some may make a round with the manager for a distance covering about 300 km; this round takes about a week to cover all the centers in the area. My question is: Is it permissible or not to shorten and combine the Salah (Prayer) in this case? It should be mentioned that during this round, we may pass by the city of one of the members participating in this round.

A: If you leave your workplace intending to travel to a distance that is eighty kilometers or more, it is permissible for you to shorten Salah for this is a distance at which travel concessions are valid, whereas whoever amongst you passes by his city where his family lives, will not be entitled to shorten Salah during his passage by this city. However, if his family does not live in this city but are accompanying him at his workplace, (Part No. 6; Page No. 418) it is permissible for him to shorten Salah on passing by his city, because he has already departed from it.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
