Quran 29:50 — Surah Al-'Ankabut, ayah 50

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

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

i govore: "Zašto mu od Gospodara njegova nisu neka čuda poslana?" Reci: "Čuda su jedino u Allaha, a ja samo jasno opominjem."
