الاحقاف — Al-Ahqaf Ayat 11
وَقَالَ الَّذِيْنَ كَفَرُوْا لِلَّذِيْنَ اٰمَنُوْا لَوْ كَانَ خَيْرًا مَّا سَبَقُوْنَآ اِلَيْهِۗ وَاِذْ لَمْ يَهْتَدُوْا بِهٖ فَسَيَقُوْلُوْنَ هٰذَآ اِفْكٌ قَدِيْمٌ
Wa qālal-lażīna kafarū lil-lażīna āmanū lau kāna khairam mā sabaqūnā ilaih(i), wa iż lam yahtadū bihī fasayaqūlūna hāżā ifkun qadīm(un).
"And those who disbelieve say of those who believe, "If it had [truly] been good, they would not have preceded us to it." And when they are not guided by it, they will say, "This is an ancient falsehood.""
