In 9:36 two words are significant; so we should take them into account in order to understand the verse correctly. First is AAiddata
- which means DURATION rather than
. The other is alshshuhoori
- which means FULL MOONS rather than
So an honest translation of the first part of the verse can be as follows: The duration of full moons in the sight of Allah is twelve full moons
Please note that in the Arabic version of the verse an expression meaning IN A YEAR is neither expressed nor implied, althouhg the translations such as the one in the "open burhan quran browser" do iclude it in parantheses: The number of months in the sight of Allah is twelve (in a year)...
So the verse is about the full moons that appear in the DURATION between the appearance of a full moon, say the scorching full moon, and its next appearance. Take the full moons which appear in the recent years, according to the nights when they appear (http://www.timeanddate.com/calendar/moonphases.html?year=2010&n=0
): 26 Jun-26 Jul-26 Jul-23 Sep
-23 Oct-21 Nov-21 Dec-19 Jan 2011-19 Jan-19 Mar-18 Apr-17 May-15 Jun15 Jul
As is seen, there are 13 full moons between the two aperanecs of the scorching full moon at the stated dates. Now if we continue from 15 July 2011 we will see that there are 12 full moons between the time span starting from July 15 2011 and ending on 15 Jul 2012.
Both durations are God's decisions, so both are correct. What might be wrong is the postponement of 15 June full moon of 2011 to the next duration of the full moons whicih what God forbis us to do in 9:37.
