اَوْ تَقُوْلُوْا لَوْ اَنَّآ اُنْزِلَ عَلَيْنَا الْكِتٰبُ لَكُنَّآ اَهْدٰى مِنْهُمْۚ فَقَدْ جَاۤءَكُمْ بَيِّنَةٌ مِّنْ رَّبِّكُمْ وَهُدًى وَّرَحْمَةٌ ۚفَمَنْ اَظْلَمُ مِمَّنْ كَذَّبَ بِاٰيٰتِ اللّٰهِ وَصَدَفَ عَنْهَا ۗسَنَجْزِى الَّذِيْنَ يَصْدِفُوْنَ عَنْ اٰيٰتِنَا سُوْۤءَ الْعَذَابِ بِمَا كَانُوْا يَصْدِفُوْنَ ( الأنعام: ١٥٧ )

Sahih International:
Or lest you say, "If only the Scripture had been revealed to us, we would have been better guided than they." So there has [now] come to you a clear evidence from your Lord and a guidance and mercy. Then who is more unjust than one who denies the verses of Allah and turns away from them? We will recompense those who turn away from Our verses with the worst of punishment for their having turned away. (Al-An'am [6] : 157)

Or you would say, “If the Book had been sent down to us, we would have been more adhering to the right path than they are.”Now there has come to you a clear sign from your Lord, and a guidance and mercy. So, who is more unjust than the one who gives the lie to the verses of Allah and turns away from them? We will recompense those who turn away from Our verses with an evil punishment, because of their turning away.
