Al-Qasas 28:86

وَمَا كُنتَ تَرْجُوٓا۟ أَن يُلْقَىٰٓ إِلَيْكَ ٱلْكِتَـٰبُ إِلَّا رَحْمَةً مِّن رَّبِّكَ ۖ فَلَا تَكُونَنَّ ظَهِيرًا لِّلْكَـٰفِرِينَ

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.
