سَلْ بَنِىٓ إِسْرَٰٓءِيلَ كَمْ ءَاتَيْنَٰهُم مِّنْ ءَايَةٍۭ بَيِّنَةٍۢ ۗ وَمَن يُبَدِّلْ نِعْمَةَ ٱللَّهِ مِنۢ بَعْدِ مَا جَآءَتْهُ فَإِنَّ ٱللَّهَ شَدِيدُ ٱلْعِقَابِ
Ask the Children of Israel how many a sign of evidence We have given them. And whoever exchanges the favor of Allah [for disbelief] after it has come to him - then indeed, Allah is severe in penalty.
O Prophet, ask the Jews about how many clear signs proving the truthfulness of the messengers were given to them by Allah. Despite this they disbelieved and turned away from them. If anyone changes the favour of Allah into disbelief and denial after being aware of it and after it has become obvious, then Allah is strong in punishing the disbelievers and the deniers.
