Al-'Ankabut 29:50

وَقَالُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ ءَايَـٰتٌ مِّن رَّبِّهِۦ ۖ قُلْ إِنَّمَا ٱلْـَٔايَـٰتُ عِندَ ٱللَّهِ وَإِنَّمَآ أَنَا۠ نَذِيرٌ مُّبِينٌ

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."
