 Tahajjud () prayer is performed at night time, and it is recommended that it be performed after first going to sleep for a part of the night.Scholars have different opinions about whether sleeping first is absolutely required or not.In Saudi Arabia during the fasting month of Ramadan, there are many people who leave the Tarawih prayers in the main masjid in a hurry so that they can go home, go to sleep, and then wake up to perform their Tahajjud prayers in the early morning.
