Surah Ar-Ra'd, Verse 7
وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ ءَايَةٌۭ مِّن رَّبِّهِۦٓ ۗ إِنَّمَآ أَنتَ مُنذِرٌۭ ۖ وَلِكُلِّ قَوْمٍ هَادٍ
Translation — Sahih International
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.
