وَلَن تَرۡضَىٰ عَنكَ ٱلۡيَهُودُ وَلَا ٱلنَّصَٰرَىٰ حَتَّىٰ تَتَّبِعَ مِلَّتَهُمۡۗ قُلۡ إِنَّ هُدَى ٱللَّهِ هُوَ ٱلۡهُدَىٰۗ وَلَئِنِ ٱتَّبَعۡتَ أَهۡوَآءَهُم بَعۡدَ ٱلَّذِي جَآءَكَ مِنَ ٱلۡعِلۡمِ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِيّٖ وَلَا نَصِيرٍ
Never will the Jews nor the Christians be pleased with you (O Muhammad Peace be upon him) till you follow their religion. Say: "Verily, the Guidance of Allah (i.e. Islamic Monotheism) that is the (only) Guidance. And if you (O Muhammad Peace be upon him) were to follow their (Jews and Christians) desires after what you have received of Knowledge (i.e. the Quran), then you would have against Allah neither any Wali (protector or guardian) nor any helper.
ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَتۡلُونَهُۥ حَقَّ تِلَاوَتِهِۦٓ أُوْلَـٰٓئِكَ يُؤۡمِنُونَ بِهِۦۗ وَمَن يَكۡفُرۡ بِهِۦ فَأُوْلَـٰٓئِكَ هُمُ ٱلۡخَٰسِرُونَ
Those (who embraced Islam from Bani Israel) to whom We gave the Book [the Taurat (Torah)] [or those (Muhammad's Peace be upon him companions) to whom We have given the Book (the Quran)] recite it (i.e. obey its orders and follow its teachings) as it should be recited (i.e. followed), they are the ones that believe therein. And whoso disbelieves in it (the Quran), those are they who are the losers. (Tafsir Al-Qurtubi. Vol. 2, Page 95).
يَٰبَنِيٓ إِسۡرَـٰٓءِيلَ ٱذۡكُرُواْ نِعۡمَتِيَ ٱلَّتِيٓ أَنۡعَمۡتُ عَلَيۡكُمۡ وَأَنِّي فَضَّلۡتُكُمۡ عَلَى ٱلۡعَٰلَمِينَ
O Children of Israel! Remember My Favour which I bestowed upon you and that I preferred you to the 'Alamin (mankind and jinns) (of your time-period, in the past).
