Al-Ma'idah' - 5:66

وَلَوْ أَنَّهُمْ أَقَامُواْ التَّوْرَاةَ وَالإِنجِيلَ وَمَا أُنزِلَ إِلَيهِم مِّن رَّبِّهِمْ لأكَلُواْ مِن فَوْقِهِمْ وَمِن تَحْتِ أَرْجُلِهِم مِّنْهُمْ أُمَّةٌ مُّقْتَصِدَةٌ وَكَثِيرٌ مِّنْهُمْ سَاء مَا يَعْمَلُونَ
[5:66]
And if they had kept up the Taurat and the Injeel and that which was revealed to them from their Lord, they would certainly have eaten from above them and from beneath their feet there is a party of them keeping to the moderate course, and (as for) most of them, evil is that which they do
If only they had stood fast by the Law, the Gospel, and all the revelation that was sent to them from their Lord, they would have enjoyed happiness from every side. There is from among them a party on the right course: but many of them follow a course that is evil.
If they had observed the Torah and the Gospel and that which was revealed unto them from their Lord, they would surely have been nourished from above them and from beneath their feet. Among them there are people who are moderate, but many of them are of evil conduct.
