actually the misconception about Islam is because of this believe… Allah said in Quran that this is the best book ever and further again it said in Quran that the Book has been made easy, so that people can understand it… by saying that one cannot understand Quran and its verses without using any tafseer etc is bringing the edge Quran had for 1200 years. In last 300 years we have this belief that Quran is meant to be understood by select group of people only and one need to follow them, and that is exactly the loop hole where many like pervaiz, mirza, wahab etc have emerged…
Quran is simple, Islam is simple, it is tradtions which has made this religion complicated and almost impossible to follow, like Illama Iqbal said something like this , yeh ummat riwayatooN maiN kho gayee…
PS: the book answer only 70%.. what about the 30%??? is there another book which answers the remaining 30%??? to me, no fitna or firqa can stand if you counter their arguments from Quran and Sahi Hadees… remember these pervaizies are very good in the proving ( and not using the word declaring as we many muslims do) ahadith wrong and that is either by the weak chain of narrations or by other rules Scholars of Islam has set…
