>>213795888'Allah tasketh not a soul beyond its scope. For it (is only) that which it hath earned, and against it (only) that which it hath deserved. Our Lord! Condemn us not if we forget, or miss the mark! Our Lord! Lay not on us such a burden as thou didst lay on those before us! Our Lord! Impose not on us that which we have not the strength to bear! Pardon us, absolve us and have mercy on us, Thou, our Protector, and give us victory over the disbelieving folk.' 2:286
Many classical jurists say that you can do Fajr at the closest manageable time OR pick a day of the year with moderate prayer times OR just do Mecca time to account for more extreme latitudes. You don't need to be getting/staying up at 2:40am if it isn't reasonable. Hope this helps brother
