وَقَالُوْا لَوْلَاۤ اُنْزِلَ عَلَیْهِ اٰیٰتٌ مِّنْ رَّبِّهٖ قُلْ اِنَّمَا الْاٰیٰتُ عِنْدَ اللّٰهِ وَاِنَّمَاۤ اَنَا نَذِیْرٌ مُّبِیْنٌ ۟

Wa qaaloo law laaa unzila 'alaihi aayaatum mir Rabbihee qul innamal aayaatu 'indal laahi wa innamaaa ana nazeerum mubeen

“Ye they say: "Why are not Signs sent down to him from his Lord?" Say: "The signs are indeed with Allah: and I am indeed a clear Warner."”
