Those whose hearts are prone to falter follow whatever is allegorical in it, seeking to create dissension by giving [their own] interpretation of it. yet only God knows its interpretation; those who are versed in knowledge say: "We believe in it; it all comes from our Lord!" However only prudent persons bear it in mind.
