Sunnah tahajud prayer in Arabic is called Lail prayer which means the night prayer. For that the midnight prayer is the sunnah prayer which is performed at night. The night at the time of this midnight prayer means that one third of the night is until dawn. One third of the night is around 1:00 to 4:00 before dawn. The midnight prayer is held at one-third of the night and the time to do it after waking up from sleep at night. But some scholars argue that the midnight prayer may not be done first. Suppose that at night, you have not slept and want to perform the midnight prayer is also okay.
