I said Several years ago the question was asked by a fellow co-worker.
But now i very well understand the whole issue that there are no prayers in Quran. The three calls for the congregation are mentioned in Quran was to convey the messages that Prophet (S) used to receive revelation in the Morning, Noon, and Evening so that everyone achieves prosperity. The present five-time prayers do not stand on logic and science repeating same words. In fact, it is like Marshal Law imposed on us and made us slaves of the time.
In an old video debate, i saw some were in the late 90s between Christian Priest Anees Sharosh and Professor Jamal Badavi. Sharosh brought this question saying if Islam was a universal way of life from God. How come God forgot the people living in the northern hemisphere as how they would offer prayers and observe fast where there is a day of six months. Professor Badawi had no answer.
Now the issue is still unanswered. How Fasting benefits mankind and God Almighty. Need answer based on logic and laws of nature. Is it like that we understood the entire message wrongly.
