Staying up late at night and its religious and worldly dangers

Question:
Honorable Shaykh, in our time there has been a lot of laxity regarding staying up late into the night, especially during vacations. What is the religious ruling on staying up late, supported by religious evidence? We ask the Shaykh (may Allah preserve him) to provide guidance and warn us of the religious and worldly dangers of staying up late. May Allah reward you with good. Thank you, my brother Khalid, may Allah bless you. Please, Shaykh Salih.

Answer:
There is no doubt that this is a serious phenomenon: staying up at night and sleeping during the day. The one who stays up at night will sleep during the day and miss the prayers at their times, and this is the greatest danger. Also, staying up at night is often for amusement, play, and fun, or for something worse, such as sins and engaging in violations. This is especially true if he stays up with a deviant group or a corrupt group, for he will be influenced by them. The Prophet (peace and blessings be upon him), as is well known, disliked sleeping before the 'Isha' prayer?
He disliked sleeping before the 'Isha' prayer, and he disliked staying up after the 'Isha' prayer, except if one needs to do so to attend to one of the affairs of the Muslims. He disliked sleeping before it and talking after it, except if one needs to do so, then only to the extent of the need, and then he would sleep (peace and blessings be upon him). Among the harms of staying up late is that it deprives a person of standing in night prayer and the witr prayer. Worse than that, it causes him to miss the Fajr prayer at its time and in congregation. Even if we say he prays Fajr, he will then sleep until the sun sets, and the times of the daytime prayers will be lost. Allah, Glorified and Exalted is He, said: . He, the Exalted, said: He called them "those who pray" and threatened them because they do not pray the required prayer at its time and in congregation, so Allah threatened them with wail.
In any case, staying up at night has religious dangers, some of which we have mentioned, and it has health dangers that affect the mind and thought. Those who stay up late often suffer from obsessive-compulsive disorder, and they suffer from illnesses that disturb their decision-making, because their brains and thoughts become disordered, and they may be afflicted with things, and they may even be afflicted with madness and the loss of reason. This has become common now; obsessions have become common, and many people complain of obsessions, tightness of the chest, and so on. So the Muslim should maintain his sleep at its proper time.
And he should maintain wakefulness at its proper time, because sleep is a rest that Allah has made a covering, a residence, and a deep sleep, meaning comfortable sleep, so that a person may rest, for he is in greater need of sleep than of food. Therefore, sleep is necessary for the Muslim, and sleep at night does not compensate for sleep during the day. If a person stays up late, my brother, seeking knowledge and reciting the Qur'an, but harms himself and also harms the obligatory duties upon him and the prayers he owes, then it is forbidden for him to do so. But if he is seeking knowledge and reading, yet he stays up for idle talk, play, heedlessness, laughter, and what is worse than that for some people, yes.
