The same old debate

I have had this debate on numerous occasions with different people. Most of them have been strongly indoctrinated by the belief that reading Quran is best done under supervision. For some reason a lot of them fear that the verses of Quran could be misleading. I, on the other hand, refer the following verse
This is the Scripture whereof there is no doubt, a guidance unto those who ward off (evil) (Verse 2:2)
There is nothing wrong with the book for Allah says so. This book is and will always be a guidance for those who believe and are righteous. A more pertinent question that arises now is what attributes would make a person righteous. For someone who has read the book knows the answer well.
It is not righteousness that ye turn your faces to the East and the West; but righteous is he who believeth in Allah and the Last Day and the angels and the Scripture and the prophets; and giveth wealth, for love of Him, to kinsfolk and to orphans and the needy and the wayfarer and to those who ask, and to set slaves free; and observeth proper worship and payeth the poor-due. And those who keep their treaty when they make one, and the patient in tribulation and adversity and time of stress. Such are they who are sincere. Such are the God-fearing. (Verse 177:2)
In this part of the world, Islam has been complicated beyond reason all thanks to the local clerics. The indoctrination of customs has been so strong that logic and reasoning is wasted. People tend to spend more time arguing on the length of the beard pyjama/trouser that they simply loose sight of the underlying problem which happens to be aqeedah.
