ANSWER:

If you have your menses and you go to bed at night, you need to wake up at fajar time to check whether you have become pure or not. Isha prayer is gone and you don’t need to make it up as you did not see your purity before midnight.

QUESTION: There is a possibility that I might get discharge from period middle of the night. Should i wakeup before fajr to check if I can pary Esha and before sunrise if I can pray fajr ?
