An-Nisa 4:113 ولولا فضل الله عليك ورحمته لهمت طايفة منهم ان يضلوك وما يضلون الا انفسهم وما يضرونك من شيء وانزل الله عليك الكتاب والحكمة وعلمك ما لم تكن تعلم وكان فضل الله عليك عظيما ١١٣

Had not the Grace of Allâh and His Mercy been upon you (O Muhammad صلى الله عليه وسلم), a party of them would certainly have made a decision to mislead you, but (in fact) they mislead none except their own selves, and no harm can they do to you in the least. Allâh has sent down to you the Book (The Qur’ân), and Al-Hikmah (Islâmic laws, knowledge of legal and illegal things i.e. the Prophet’s Sunnah - legal ways), and taught you that which you knew not. And Ever Great is the Grace of Allâh unto you (O Muhammad صلى الله عليه وسلم).
