Quran 51:52 from Surah Adh-Dhaariyat on Divine Marvels.
كَذَٰلِكَ مَآ أَتَى ٱلَّذِينَ مِن قَبۡلِهِم مِّن رَّسُولٍ إِلَّا قَالُواْ سَاحِرٌ أَوۡ مَجۡنُونٌ
English translation: Likewise not came (to) those before them before them any Messenger but they said A magician or a madman
Transliteration: kadhalika ma ata alladhina min qablihim min rasulin illa qalu sahirun aw majnunun
