28:86
وَمَا كُنْتَ تَرْجُٓوا اَنْ یُلْقٰٓى اِلَیْكَ الْكِتَابُ اِلَّا رَحْمَةً مِنْ رَبِّكَ فَلَا تَكُونَنَّ ظَهٖیرًا لِلْكَافِرٖینَؗ
Wama kunta tarjoo an yulqa ilayka alkitabu illa rahmatan min rabbika fala takoonanna thaheeran lilkafireena

Saheeh International
Thou hadst no hope that the Scripture would be inspired in thee; but it is a mercy from thy Lord, so never be a helper to the disbelievers
