Can I Use Two Different Calculation and Estimation (Taqdir) Methods for Isha and Fajr?

Hanafi FiqhShafi'i Fiqh

Answered by Mawlana Ilyas Patel


I live in Scandinavia, where Isha and Fajr do not appear under certain months from late spring to late summer. Even Isha, according to the red twilight (Shafaq al-Ahmar), will become very late and then stop to appear.

When I use an estimation (taqdir) for my prayer times, is it a strict condition that I use the same method for Isha and Fajr, or can I use different methods for the two prayers?

Let’s say as an example that says I use Aqrab al-Bilad for Isha and Aqrab al-Ayyam for Fajr.


In the Name of Allah, the Most Merciful and Compassionate.

I pray you are in good faith and health. Thank you for your question.

You may use Aqrab al-Bilad for Isha and Aqrab al-Ayyam for Fajr.

The Fuqaha have mentioned different methods in calculating the times for Fajr and Isha prayer at extreme latitudes. In areas above 48 latitudes, on certain days of the summer, Maghrib time directly goes into Fajr time. There is no time for the Isha prayer.

There are four methods for estimating the ending time of Isha and the beginning time of Fajr:

1) Aqrab al-Ayyam: On certain days when Isha time fails to appear, the time will be set according to the last day when dawn actually did rise. For example, on the final day, when dawn set, it was 1:08 a.m. So, throughout the period when there is no apparent beginning time for Fajr, we will set the time at 1:08 a.m. This is known as “Aqrab al-Ayyam.”

2) Nisf al-Layl: The time between sunset and sunrise is divided into two parts. The first half is considered night, and the second morning, meaning the time for Isha will end, and the time for Fajr will commence when the first half ends. This is known as “Nisf al-Layl.”

3) Aqrab al-Bilad. This method is by looking at the nearest place where the time for Isha does appear, and the time is set according to their time. This is known as “Aqrab al-Bilad.”

4) Sub al-Lail: The last method divides the time between sunset and sunrise into seven parts. The first six parts are considered the night in which you may perform the isha prayer, and the final part is considered to be the commencement for dawn, the Fajr prayer.
