Quran 46:11 from Surah Al-Ahqaf on Divine Marvels.
وَقَالَ ٱلَّذِينَ كَفَرُواْ لِلَّذِينَ ءَامَنُواْ لَوۡ كَانَ خَيۡرٗا مَّا سَبَقُونَآ إِلَيۡهِۚ وَإِذۡ لَمۡ يَهۡتَدُواْ بِهِۦ فَسَيَقُولُونَ هَٰذَآ إِفۡكٞ قَدِيمٞ
English translation: And say those who disbelieve of those who believe If it had been good not they (would) have preceded us to it And when not they (are) guided by it they say This (is) a lie ancient
Transliteration: waqala alladhina kafaru lilladhina amanu law kana khayran ma sabaquna ilayhi wa-idh lam yahtadu bihi fasayaquluna hadha if'kun qadimun
