Criticism of Islam has existed since Islam 's formative stages . Early written disapproval came from Christians and Jews as well as from some former Muslims such as Ibn al-Rawandi . Later the Muslim world itself suffered criticism . Western criticism has grown in the 21st century especially after the September 11 attacks and other terrorist incidents . As of 2014 , about a quarter of the world 's countries and territories ( 26 % ) had anti-blasphemy and anti-apostasy laws or policies , of which 13 nations , all of which were Muslim majority nations , had the death penalty for apostasy
