وَقَالُواْ لَوۡلَآ أُنزِلَ عَلَيۡهِ ءَايَٰتٞ مِّن رَّبِّهِۦۚ قُلۡ إِنَّمَا ٱلۡأٓيَٰتُ عِندَ ٱللَّهِ وَإِنَّمَآ أَنَا۠ نَذِيرٞ مُّبِينٌ٥٠

waqālū lawlā unzila ʿalayhi āyātun min rabbihi qul innamā l-āyātu ʿinda l-lahi wa-innamā anā nadhīrun mubīnun

But they say, "Why are not signs sent down to him from his Lord?" Say, "The signs are only with Allāh, and I am only a clear warner."
