Aisha reported that the Messenger of Allah ﷺ recited this verse, "It is He who has sent down to you the Book. In it are verses precise in meaning, which are the foundation of the Book, and others that are open to interpretation. As for those in whose hearts is deviation, they follow what is open to interpretation in it, seeking discord and seeking its interpretation. But no one knows its interpretation except Allah. And those firmly grounded in knowledge say, 'We believe in it. All of it is from our Lord.' Yet none take heed except those of understanding" [Al Imran 3:7].She said that the Messenger of Allah then said, "So when you see those who pursue what is open to interpretation in it, those are the ones Allah has named, so beware of them."
تلا رسول الله ﷺ هذه الآية: {هو الذي أنزل عليك الكتب منه ءايت محكمت هن أم الكتاب وأخر متشبهت فأما الذين في قلوبهم زيغ فيتبعون ما تشبه منه ابتغاء الفتنة وابتغاء تأويله وما يعلم تأويله إلا الله والراسخون في العلم يقولون ءامنا به كل من عند ربنا وما يذكر إلا أولوا الألبب}[سورة آل عمران: ٧] قالت: قال رسول الله: فإذا رأيت الذين يتبعون ما تشابه منه فأولئك الذين سمى الله فاحذروهم.
