it is he who has revealed the book to you. some of its verses are absolutely clear and lucid and these are the core of the book. others are ambiguous. those in whose hearts there is perversity always go about the part which is ambiguous seeking mischief and seeking to arrive at its meaning arbitrarily although none knows their true meaning except allah. on the contrary those firmly rooted in knowledge say we believe in it it is all from our lord alone. no one derives true admonition from anything except the men of understanding.
هو الذي أنزل عليك الكتاب منه آيات محكمات هن أم الكتاب وأخر متشابهات فأما الذين في قلوبهم زيغ فيتبعون ما تشابه منه ابتغاء الفتنة وابتغاء تأويله وما يعلم تأويله إلا الله والراسخون في العلم يقولون آمنا به كل من عند ربنا وما يذكر إلا أولو الألباب
