The correct ‘aqeedah is the foundation of Islaam and the foundation stone of the Islamic nation. It is known through evidences of the sharee’ah from the Book and the Sunnah, that one’s actions and statements can only be correct and acceptable to Allaah when they arise from a correct ‘aqeedah. If, however, the ‘aqeedah is not correct then then actions and statements that arise due to it are invalid.
The evidences in the clear Book of Allaah and in the Sunnah of His truthful Messenger, sallallaahu ‘alayhi wa sallam, show the correct ‘aqeedah in brief, to be: eemaan in Allaah, His Angels, His Books, His Messengers, the Last Day, and Predestination – the good and the bad of it. These six matters are the fundamentals of the correct ‘aqeedah with which Allaah, the Almighty, revealed His Book and sent His Messenger Muhammad, sallallaahu ‘alayhi wa sallam.
