Hazrat Aisha (may Allah be pleased with her) narrated that the Messenger of Allah (peace and blessings be upon him) recited this verse: "He it is Who has sent down to you the Book; in it are clear and firm verses—they are the foundation of the Book—and others are ambiguous. So as for those in whose hearts is deviation, they follow that which is ambiguous from it, seeking discord and seeking its interpretation. But no one knows its true interpretation except Allah. And those firmly grounded in knowledge say: 'We believe in it; all is from our Lord.' And none take heed except those of understanding." Hazrat Aisha (may Allah be pleased with her) said that the Prophet (peace and blessings be upon him) said: When you see those who pursue the ambiguous verses, then know that they are those whom Allah has mentioned (in the above Ayah), so beware of them.

Hazrat Jundub bin Abdullah (may Allah be pleased with him) narrated that the Holy Prophet (peace and blessings be upon him) said: Recite this Qur'an as long as your hearts are united or inclined towards it, but when you begin to differ and dispute, then stand up (stop reciting).
