If you're going to bed late at night, read the story.

And the dog stays awake all night and sleeps before Fajr. So it is deprived of blessings. It is a matter of concern, the Sunnah of the Prophet (peace be upon him) is to sleep after performing the Isha prayer. At the end of the night, he wakes up and performs Tahajjud, because Allah descends to the first heaven in the last third of the night and calls his servants to pray and ask for forgiveness. And we? We fall asleep at this time after being busy with forbidden things on mobile phones and the internet. And we have no idea about Fajr. There are many of us who go to sleep right when they hear the call to Fajr in the mosque. They think, Alas, it is time to sleep. But they do not think that when the call to prayer is over, they fall asleep after performing the prayer.
