1705. Narrated ‘Aaisha (radhi Allaahu anha) : Allaah’s Messenger (Sallallaahu Alaihi Wasallam) recited the Verse :

“It is He Who has sent down to you [O Muhammad (Sallallaahu Alaihi Wasallam)] the Book (this Qur’aan). In it are Verses that are entirely clear, they are the foundation of the Book, [and those are the Verses of  Al-Ahkaam (commandments etc.), Al-Faraa’id (obligatory duties) and Al-Hudood (legal laws for the punishmentof theives, adulterers etc.)], and others not entirely clear. So as for those in whose hearts there is a deviation (from the Truth), they follow, that which is not entirely clear thereof, seeking Al-Fitnah (polytheism and trials etc.) and seeking for its hidden meanings; but none knows its hidden meanings save Allaah. And those who are firmly grounded in knowledge say : ‘We believe in it; the whole of it (clear and unclear Verses) are from our Lord.’ And none receive admonition except men of understanding.” (V.3:7)

‘Aaisha added : “Then Allaah’s Messenger (Sallallaahu Alaihi Wasallam) said, ‘if you see those who follow thereof that is not entirely clear, then they are those whom Allaah has named [(as having deviation (from the Truth)]. So beware of them.’ “
