Would I still get the same reward for Ishraq as compared to staying up?
Ishraaq salaah is performed at approximately 20 minutes after sunrise. We
advise you perform your Fajr salaah just before sunrise and engage in any
act that may keep you awake till Ishraaq time and thereafter fulfil your
sleep. If the reason for feeling sleepy is sleeping late at night, then you
should also make adjustments in that.
and Allah Ta’ala Knows Best
