Prayer: What are the conditions for a traveler to shorten four-rak‘ah prayers?

Question #638:

What are the conditions for the four-rak‘ah prayers to become obligatorily shortened on the traveler?

Answer #638:

They are eight conditions:
i. The traveled distance should be at least eight continuous shar‘ī farsakhs, either going or returning, or altogether provided that the going distance is not less than four shar‘ī farsakhs.

ii. The intent to travel the distance should exist from the time of departure. Hence if one does not intend to cover the distance, or intends a shorter one and then intends to travel to another place after reaching his destination, whose distance from the first destination is less than the shar‘ī distance, but more than the shar‘ī distance from his home, one will not pray shortened.

iii. The continuation of intent until the distance is covered. Thus if one changes his mind before covering four shar‘ī farsakhs or hesitates, the rule of travel will not apply to him after that, but the shortened prayers he performed before changing his intention must be said again by obligatory caution.

iv. That there be no intention to interrupt one’s journey while covering the distance by passing through one’s hometown, or by intending to stay ten days or more in another place.

v. That the journey be a lawful one according to Islamic law. Thus if the journey is a sinful or ḥarām one, whether it is such in itself like fleeing a holy war, or its purpose is ḥarām, such as traveling to commit highway robbery, for example, the rule of the traveler will not apply to it.

vi. That the traveler not be one of those who live a migrant life, like some Bedouins who do not have a fixed location and wander through deserts and stay near water, grass and pastures.

vii. That traveling should not be one’s job, such as a driver, a sailor, a person who hires out animals of burden, and so on. One whose job is done in traveling is also treated like the aforementioned.

viii. Reaching the tarakhkhuṣ limit, namely the point from where one cannot hear the town’s adhān which is normal and said without a loudspeaker.
