Surah Ar-Ra'd, Verse 7

وَيَقُولُ ٱلَّذِينَ كَفَرُواْ لَوۡلَآ أُنزِلَ عَلَيۡهِ ءَايَةٞ مِّن رَّبِّهِۦٓۗ إِنَّمَآ أَنتَ مُنذِرٞۖ وَلِكُلِّ قَوۡمٍ هَادٍ٧

wayaqūlu alladhīna kafarū lawlā unzila ʿalayhi āyatun min rabbihi innamā anta mundhirun walikulli qawmin hādin

And those who disbelieved say, "Why has a sign not been sent down to him from his Lord?" You are only a warner, and for every people is a guide.
