Quran was revealed in approx 22 and a half years. Does anyone have the exact total time for this with a authentic source?

    May I ask what is the value gained by such knowledge? How is this useful?

    @mtk This still doesn't provide a rationale for spending time to research this subject. You already state that it took 22-23 years. Why would you spend time or effort to make this estimate more accurate? You could spend your time (and potential answerers' time) on something more useful.

From the Qur'an and the tradition, scholars say that Qur'an was revealed twice.

Once, it was revealed in full at the night of Qadr. Although scholars have not reached a consensus as to its time and place.

Second time it was gradually revealed in a span of 23 years.

  • Please address the second question as well. Although OP should have asked it in another question. Commented Feb 9, 2014 at 19:22
