The Distance Rule
The majority consensus for a journey to qualify as 'Safar' is approximately 48 miles (77-78 km). This is based on the classical measurement of 4 'Burud' (16 Farsakh).
The Residence Rule
If you plan to stay at your destination for more than:
15 days (Hanafi) OR
4 days (Shafi'i, Maliki, Hanbali)
You count as a Resident immediately upon arrival.
What concessions do I get?
Allah intends ease for His servants. Once you qualify as a Musafir, you are granted specific dispensations:
- Qasr (Shortening): You must (Hanafi) or permitted to (Others) shorten Dhuhr, Asr, and Isha from 4 Rakats to 2. Maghrib (3) and Fajr (2) remain unchanged.
- Breaking Fast: It is permissible to not fast in Ramadan if travelling is difficult, though you must make it up later (Qada).
- Wiping on Socks (Masah): The period extends from 1 day to 3 days/nights.
Vital Nuance: When does it start?
You cannot shorten prayers at home before you leave. You only become a traveller once you leave the building boundaries of your city. E.g. If you live in London, you become a traveller once you pass the M25 ring road concept.
Common Scenarios
The Commuter
If you commute daily to a workplace 60 miles away, are you a
traveller?
Yes. As long as you do not intend to stay there for
the residence duration. You shorten your prayers at work.
The Student
If you go to university for a term:
Since a term is longer than 15 days, you are a Resident at your university city. You pray full prayers. When you travel
back home for weekends (if >48 miles), you are a traveller during
the journey.
