Is it permissible to shorten the prayer when traveling on Friday morning and returning on Tuesday evening?

If the travel distance allows for shortening prayers (83 km), then it is permissible to shorten the prayer before returning. The duration for which one may shorten prayers is a matter of scholarly disagreement. Some scholars hold that a traveler may shorten prayers if they intend to stay for less than four days, excluding the days of arrival and departure. Others have set the limit at fifteen days, while still others at four days, with disagreement regarding the inclusion of the days of arrival and departure in the count.
