أَوْ تَقُولُوا لَوْ أَنَّا أُنزِلَ عَلَيْنَا الْكِتَابُ لَكُنَّا أَهْدَىٰ مِنْهُمْ ۚ فَقَدْ جَاءَكُم بَيِّنَةٌ مِّن رَّبِّكُمْ وَهُدًى وَرَحْمَةٌ ۚ فَمَنْ أَظْلَمُ مِمَّن كَذَّبَ بِآيَاتِ اللَّهِ وَصَدَفَ عَنْهَا ۗ سَنَجْزِي الَّذِينَ يَصْدِفُونَ عَنْ آيَاتِنَا سُوءَ الْعَذَابِ بِمَا كَانُوا يَصْدِفُونَ (157)
(6:157) Nor may you claim that: 'Had the Book been revealed to us, we would have been better guided than they.' Surely clear evidence has come to you from your Lord, which is both a guidance and a mercy. Who, then, is more unjust than he who gave the lie to the signs of Allah and turned away from them? *138 And We shall soon requite those who turn away from Our signs with a severe chastisement for having turned away.
*138). 'Signs of Allah' include the teachings embodied in the Qur'an. They are also manifest in the noble life of the Prophet (peace be on him), and the pure lives of those who believed in him. Tley also include the natural phenomena to which the Qur'an refers in support of its message.
