There are persons to whom we preach the Islam of the Quran who react to the wide divergence between it and the Islam of the sectarians by saying: “You are simplifying the religion. How can religion be so easy to practice?” and accuse those who defend the Islam of the Quran by subjectivism, attempting to suit it to their own ends. However, all that they do is but to display their ignorance of the verses of the Quran. According to the Quran, there is nothing complex about Islam. If you are advocating a ‘difficult and complex’ religion, it is not the Islam of the Quran;.for it is as simple as the religion of Abraham.
