It is clear that our prophet(PBUH) prayed 8 rakaats for taraweeh.
But, I saw most of the masjids having 20 rakaats for taraweeh. since, Umar(R.A) made the taraweeh to 20 rakaats.
What is the reason for that?
I have no doubt about Hazrat Umar(R.A). I know muhammad(PBUH) told that "If there were a Prophet after me verily it would be `Umar."
What made him to change the rakaat count?
