وَكَذَٰلِكَ أَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ ۚ فَٱلَّذِينَ ءَاتَيْنَٰهُمُ ٱلْكِتَٰبَ يُؤْمِنُونَ بِهِۦ ۖ وَمِنْ هَٰٓؤُلَآءِ مَن يُؤْمِنُ بِهِۦ ۚ وَمَا يَجْحَدُ بِـَٔايَٰتِنَآ إِلَّا ٱلْكَٰفِرُونَ
In like manner We have revealed unto thee the Scripture, and those unto whom We gave the Scripture aforetime will believe therein; and of these (also) there are some who believe therein. And none deny Our revelations save the disbelievers.
