The number of the total population has been taken from The CIA World's Facts Book which can be found at: http://www.odci.gov/cia/publications/factbook
I've used it to verify the total number of population in every country but it lacks the percentage of Muslims in each country so I have used another statistic located at: http://www.flash.net/~royal/country.html
In 1986, the Muslim Education Trust organization (MET) located in the United Kingdom and directed by Ghulam Sarwar, obtained the 1971 census and information given by Embassies of the respective countries in London. The 1971 census showed the Independent Muslim countries population was around 784.5 Million and the Muslim Minorities countries had around 308 Million Muslim.
As for the U.N., I've used Briticana Encyclopidia for 1994 and for 1995 to get the growth rates. Briticana took those statistics from the U.N.
So, I've applied the percentage of Muslims (taken from MET) to the number of people (taken from CIA) to each country using Microsoft Excel then it was easy to get the final number.
But that is not all. I had more accurate statistics to some countries so I've used them directly.
