Methodology - 'Manhaj' Monotheism - Tawheed

A Statement of Absolute Reality by [Saudi King Abdul Azeez (rahimahullaah)] About the Cause of Most of The Fitan between the Muslims

King Abdul Azeez (rahimahullaah) said:

Do you know what destroys the religion and (is the cause of) most of the trials between the Muslims? This has not (happened) except due to differing between the Muslims and their lack of being in agreement (i.e. differing in Aqeedah and Manhaj).
