سَلْ بَنِىٓ إِسْرَٰٓءِيلَ كَمْ ءَاتَيْنَٰهُم مِّنْ ءَايَةٍۭ بَيِّنَةٍۢ ۗ وَمَن يُبَدِّلْ نِعْمَةَ ٱللَّهِ مِنۢ بَعْدِ مَا جَآءَتْهُ فَإِنَّ ٱللَّهَ شَدِيدُ ٱلْعِقَابِ
Ask of the Children of Israel how many a clear revelation We gave them! He who altereth the grace of Allah after it hath come unto him (for him), lo! Allah is severe in punishment.
