Question:
When travelling, many institutions give different times using different methods for calculating prayer times. One might say 3:40 AM for Fajr, while another says 4:30 AM.
Who should we follow when abroad?
Answer:
When you are abroad, follow the prayer times of the masjid that is closest to you, or the one where you usually pray. This issue is a matter of scholarly ijtihad (independent reasoning), and the various methods of calculation are all based on valid scholarly opinions. Whichever reliable timetable you choose to follow in this situation is permissible.
