Read and reflect on verse 735 from Surah Al-Maaida: and if they would but truly observe the Torah and the Gospel and all [the revelation] that has been bestowed from on high upon them by their Sustainer...
وَلَوْ أَنَّهُمْ أَقَامُوا التَّوْرَاةَ وَالْإِنْجِيلَ وَمَا أُنْزِلَ إِلَيْهِمْ مِنْ رَبِّهِمْ لَأَكَلُوا مِنْ فَوْقِهِمْ وَمِنْ تَحْتِ أَرْجُلِهِمْ ۚ مِنْهُمْ أُمَّةٌ مُقْتَصِدَةٌ ۖ وَكَثِيرٌ مِنْهُمْ سَاءَ مَا يَعْمَلُونَ
and if they would but truly observe the Torah and the Gospel and all [the revelation] that has been bestowed from on high upon them by their Sustainer, they would indeed partake of all the blessings of heaven and earth. Some of them do pursue a right course; but as for most of them -vile indeed is what they do!
