We need not waste our time and energy on such useless claims of numerical miracles in the Quran. 

It would be better if we let Muslim scholars themselves refute such claims. The largest Muslim Fatawa website writes:


I read some 'miracles' of the qur'an recently. These included many things such as the 3 stages of embryos, the orbits of planets, etc etc. However, one of them claimed that the word yawm (day) is mentioned 365 times in the qur'an, and the word qamar is mentioned 12 times in the quraan. I forget how many times the word ayyaam is mentioned. However, a friend pointed out that the islamic calender does not have 365 days in it. What does this mean about the islamic calender? That it is wrong? Or that God knew that most of the world would use the Gregorian calender and that this is a sign that it is the correct one?.


Praise be to Allah.


Many people are infatuated by the different types of miracles in the Qur’aan, including the “numerical miracles”. In newspapers and magazines and on the internet they publish lists of words that are repeated a number of times that corresponds to their structure, and words that are repeated the same number of times as their opposites. They also claim that the word yawm (day) is repeated 365 times and the word shahr (month) is repeated 12 times, and they do this with other words too, such as al-malaa’ikah (angels) and al-shayaateen (devils), and al-dunya (this world) and al-aakhirah (the Hereafter), etc.  

Many people think that these numbers are true and that this is one of the miracles of the Qur’aan, but they do not distinguish between subtleties and miracles. Writing a book which contains a specific number of certain words is something that anyone can do; what is so miraculous about that? ...

It should be noted that some people have taken this beyond mere statistics. Some of them have used these numbers to foretell when the state of Israel will fall, and others have used them to say when the Day of Judgement will be. One of the latest fabrications against the Book of Allaah is that which they have published saying that the Qur’aan foretold the explosions in the towers in New York! Based on the number of the verse in al-Tawbah, and the number of the soorah and juz’. All of that is toying with the Book of Allaah which is caused by ignorance of the true nature of the miracle of the Book of Allaah. 


By examining the statistics presented by those who have published these numbers, we find that they did not get the numbers of some phrases right, and some of them have been selective in the way they counted the words, and that is so that they might reach the conclusion they want and that they think is in the Book of Allaah.
