The World Federation One Stop Fiqh

Ruling 1293

With regard to someone whose profession is travelling, if he travels for another purpose, such as ziyārah or hajj, he must perform qaṣr prayers unless he is commonly known to be a frequent traveller, such as someone who always travels three days in a week. However, if, for example, a car driver is hired for a ziyārah trip and on that trip he also performs ziyārah, he must perform tamām prayers.
