Surah Al-Qasas, Verse 86

وَمَا كُنتَ تَرۡجُوٓاْ أَن يُلۡقَىٰٓ إِلَيۡكَ ٱلۡكِتَٰبُ إِلَّا رَحۡمَةٗ مِّن رَّبِّكَۖ فَلَا تَكُونَنَّ ظَهِيرٗا لِّلۡكَٰفِرِينَ٨٦

wamā kunta tarjū an yul'qā ilayka l-kitābu illā raḥmatan min rabbika falā takūnanna ẓahīran lil'kāfirīna

And you were not expecting that the Book would be conveyed to you, but [it is] a mercy from your Lord. So do not be an assistant to the disbelievers.
