In this era of confusion, innovation, and division, it is essential for Muslims to monitor their beliefs and their approach to Islam, so that they may be certain that they are following the path of the Prophet (blessings and peace of Allah be upon him) and the early generation of pious Muslims (the salaf). Without careful attention, a Muslim may live his or her whole life following a deviant path filled with innovation, thinking that he or she is doing the right thing, only to find out – when it is too late – that this path only leads to hell.

This is a book which should be on every Muslim’s bookshelf, so that they will have at their fingertips a concise and readily-accessible reference for the basic issues of their religion.
