قُلۡ أَرَءَيۡتُمۡ إِن كَانَ مِنۡ عِندِ ٱللَّهِ وَكَفَرۡتُم بِهِۦ وَشَهِدَ شَاهِدٞ مِّنۢ بَنِيٓ إِسۡرَـٰٓءِيلَ عَلَىٰ مِثۡلِهِۦ فَـَٔامَنَ وَٱسۡتَكۡبَرۡتُمۡۚ إِنَّ ٱللَّهَ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّـٰلِمِينَ
Say: "Tell me! If this (Quran) is from Allah, and you deny it, and a witness from among the Children of Israel ('Abdullah bin Salam) testifies that this Quran is from Allah [like the Taurat (Torah)], so he believed (embraced Islam) while you are too proud (to believe)." Verily! Allah guides not the people who are Zalimun (polytheists, disbelievers and wrong-doing).
وَقَالَ ٱلَّذِينَ كَفَرُواْ لِلَّذِينَ ءَامَنُواْ لَوۡ كَانَ خَيۡرٗا مَّا سَبَقُونَآ إِلَيۡهِۚ وَإِذۡ لَمۡ يَهۡتَدُواْ بِهِۦ فَسَيَقُولُونَ هَٰذَآ إِفۡكٞ قَدِيمٞ
And those who disbelieve (strong and wealthy) say of those who believe (weak and poor): "Had it (Islamic Monotheism to which Muhammad SAW is inviting mankind) been a good thing, they (weak and poor) would not have preceded us thereto!" And when they have not let themselves be guided by it (this Quran), they say: "This is an ancient lie!"
وَمِن قَبۡلِهِۦ كِتَٰبُ مُوسَىٰٓ إِمَامٗا وَرَحۡمَةٗۚ وَهَٰذَا كِتَٰبٞ مُّصَدِّقٞ لِّسَانًا عَرَبِيّٗا لِّيُنذِرَ ٱلَّذِينَ ظَلَمُواْ وَبُشۡرَىٰ لِلۡمُحۡسِنِينَ
And before this was the Scripture of Musa (Moses) as a guide and a mercy. And this is a confirming Book (the Quran) in the Arabic language, to warn those who do wrong, and as glad tidings to the Muhsinun (good-doers - see V. 2:112).
