Staying up late is inherently disliked, especially for those who miss Fajr prayer because of it. Some scholars have even made it obligatory to sleep early for anyone who misses the prayer due to staying up late. A person is considered sinful if missing the prayer is due to sleeping late or neglecting the means that help one wake up.
