How can one reconcile studying and staying up late for it with maintaining the Fajr prayer?

Prayer performed on time is the most beloved deed to Allah after belief in Him. It is the most important means by which a servant draws near to his Lord, and Allah has enjoined it at specific times. Therefore, a Muslim must observe it and prioritize it over worldly matters. Study and sleep should be organized in a way that allows for performing Fajr prayer, seeking Allah's help and sleeping early, which aids in waking up for the prayer. The study time previously allocated for staying up late can be compensated at another time, preferably after Fajr prayer, due to the blessedness of this time. If you sleep early, you can revise in the morning with energy. If you cannot, you can revise at other times, such as after Asr or Maghrib. The important thing is to allocate sufficient time for revision without affecting the performance of obligatory prayers. If you take the necessary precautions and then oversleep and miss the prayer, there is no sin upon you.
