There is no prayer method or timings in Quran. No 2 Islamist admit it and excuses they come up with are strange. One says it was there already, one says Quran would have been so big then(Dr. Farhat Hashmi of Alhuda!) and what not else.
But think why would then they need the whole hadithy story of meraaj? Somewhere they are contradicting themselves when they say it was only the continuation of what was there already... In Urdu they say, Jhoot ke paer nahi hotay!
