Fatwaa.net - Fatawa | I live in Istanbul and the prayer time according to the calendar (online) is 3:30, while the adhan is at 4:20. I pray according to the calendar because I see that the adhan is delayed. Also, during Ramadan, we rely on the calendar instead of the imsak because they depend on the true dawn. Is my prayer valid when I perform it before the adhan, or do I need to make it up?

Question

Also, during Ramadan, we rely on the calendar instead of the imsak because they depend on the true dawn. Is my prayer valid when I perform it before the adhan, or do I need to make it up?

Answer

I say, and with God's success: You should adhere to the call to prayer of your country, and the calendar should match the call to prayer in your country, and God knows best.
