Surah Al-'Ankabut — Ayah 50 (29:50)
وَقَالُواْ لَوۡلَآ أُنزِلَ عَلَيۡهِ ءَايَٰتٞ مِّن رَّبِّهِۦۚ قُلۡ إِنَّمَا ٱلۡأٓيَٰتُ عِندَ ٱللَّهِ وَإِنَّمَآ أَنَا۠ نَذِيرٞ مُّبِينٌ ٥٠
English translation (Saheeh International)
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."
Brief commentary
The idolaters said, “Why have no miracles been given to Muhammad from his Lord, like those miracles given to the messengers before him?” O Messenger! say to them: “Miracles are only in the control of Allah, may He be glorified; He grants them whenever He wishes. It is not in my power to bring them; I am only a clear warner to you of the punishment of Allah.”
