The Quran says that truth can only be reached by reason and based on God’s Book.. The defenders of the traditionalist Islam, opponents of this thesis of the Quran, do their utmost to obliterate this conjecture, deviating the naive people’s rational and logical tendencies towards the acceptance and adoption of sectarian dictates transformed into deep-seated traditions. The devotees of these traditions, who have replaced God’s revelation with man-made religion, argue, on the grounds that the majority of the believers have acted in emulation of their ancestors, that their forefathers could not have erred in their practices, so ipso facto they must be duly obeyed.
20 –Yet, some people argue about God without knowledge, without guidance, and without an enlightening book.
21. And when they are told, “Follow what God has sent down,” they say, “No, we follow the ways that we found our parents doing.”
31 Luqmaan, 20-21
We observe from the above verses that the ways of our ancestors were opposed to God’s revelation at the time of the Prophet, in total disregard of the verses of the Quran which they tried to replace by an infinite number of fabricated sources defying intellect as such.
