وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لِلَّذِينَ ءَامَنُوا۟ لَوْ كَانَ خَيْرًا مَّا سَبَقُونَآ إِلَيْهِ ۚ وَإِذْ لَمْ يَهْتَدُوا۟ بِهِۦ فَسَيَقُولُونَ هَـٰذَآ إِفْكٌ قَدِيمٌ

Those who disbelieve say of the believers, ‘If there were any good in this Quran, they would not have believed in it before we did,’and, since they refuse to be guided by it, they say, ‘This is an ancient fabrication.’
And those who disbelieve (the strong and wealthy) say of those who believe (the weak and poor): "Had it (Islâmic Monotheism to which Muhammad صلى الله عليه وسلم is inviting mankind) been a good thing, they (the weak and poor) would not have preceded us thereto!" And when they have not let themselves be guided by it (this Qur’ân), they say: "This is an ancient lie!"
