• Should We Busy The People With "Where Is Allaah" & Other Matters Of Belief? - Shaykh Abdul-Azeez ibn Baaz {rahimahullaah}
Question: Some people say, “It is not correct to busy the general folk with affirmation of the matters of Aqeedah (Belief) such as the Highness of Allaah above the creation (al-’Uluww) and other such matters”?
Answer: The ‘Aqeedah is the most important of affairs. The Prophet {sallAllaahu 'alayhi wa sallam} was in Makkah for thirteen years, and all of that time was given to the Aqeedah. The Aqeedah is the foundation of the Religion.
