القرآن:١٤:٥٢ –

هَٰذَا بَلَاغٌ لِلنَّاسِ وَلِيُنْذَرُوا بِهِ وَلِيَعْلَمُوا أَنَّمَا هُوَ إِلَٰهٌ وَاحِدٌ وَلِيَذَّكَّرَ أُولُو الْأَلْبَابِ  

{هذا} القرآن {بلاغ للناس} أي أنزل لتبليغهم {ولينذروا به وليعلموا} بما فيه من الحجج {أنما هو} أي الله {إله واحد وليذكّر} بإدغام التاء في الأصل في الذال يتعظ {أولوا الألباب} أصحاب العقول.
