Assalamu Alaikum,
I heard from some people that tahajjud prayer should be performed after waking up from deep sleep. But also read in some other places that it is not mandatory to wake up from deep sleep, even we can pray after a 5 minutes nap. What is the procedure please somebody enlighten me.
If I fall asleep early at night I can't wake up for tahajjud, so I used to practice it often without deep sleep.
JazakAllah Khair.
