وَقَالَتِ ٱلْيَهُودُ يَدُ ٱللَّهِ مَغْلُولَةٌ ۚ غُلَّتْ أَيْدِيهِمْ وَلُعِنُوا۟ بِمَا قَالُوا۟ ۘ بَلْ يَدَاهُ مَبْسُوطَتَانِ يُنفِقُ كَيْفَ يَشَآءُ ۚ وَلَيَزِيدَنَّ كَثِيرًۭا مِّنْهُم مَّآ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ طُغْيَٰنًۭا وَكُفْرًۭا ۚ وَأَلْقَيْنَا بَيْنَهُمُ ٱلْعَدَٰوَةَ وَٱلْبَغْضَآءَ إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ ۚ كُلَّمَآ أَوْقَدُوا۟ نَارًۭا لِّلْحَرْبِ أَطْفَأَهَا ٱللَّهُ ۚ وَيَسْعَوْنَ فِى ٱلْأَرْضِ فَسَادًۭا ۚ وَٱللَّهُ لَا يُحِبُّ ٱلْمُفْسِدِينَ
The Jews say: Allah's hand is fettered. Their hands are fettered and they are accursed for saying so. Nay, but both His hands are spread out wide in bounty. He bestoweth as He will. That which hath been revealed unto thee from thy Lord is certain to increase the contumacy and disbelief of many of them, and We have cast among them enmity and hatred till the Day of Resurrection. As often as they light a fire for war, Allah extinguisheth it. Their effort is for corruption in the land, and Allah loveth not corrupters.
Surah Al-Maaida(5:64)
