25:27
وَ يَوْمَ يَعَضُّ ٱل ظَّالِمُ عَلَىٰ يَدَيْ هِ يَقُولُ يَٰ لَيْتَ نِى ٱتَّخَذْ تُ مَعَ ٱل رَّسُولِ سَبِيلًا
And the Day the wrongdoer will bite on his hands [in regret] he will say, "Oh, I wish I had taken with the Messenger a way.
3:119
هَٰٓ أَنتُمْ أُو۟لَآءِ تُحِبُّ ونَ هُمْ وَ لَا يُحِبُّ ونَ كُمْ وَ تُؤْمِنُ ونَ بِ ٱلْ كِتَٰبِ كُلِّ هِۦ وَ إِذَا لَقُ و كُمْ قَالُ وٓا۟ ءَامَ نَّا وَ إِذَا خَلَ وْا۟ عَضُّ وا۟ عَلَيْ كُمُ ٱلْ أَنَامِلَ مِنَ ٱلْ غَيْظِ قُلْ مُوتُ وا۟ بِ غَيْظِ كُمْ إِنَّ ٱللَّهَ عَلِيمٌۢ بِ ذَاتِ ٱل صُّدُورِ
Here you are loving them but they are not loving you, while you believe in the Scripture - all of it. And when they meet you, they say, "We believe." But when they are alone, they bite their fingertips at you in rage. Say, "Die in your rage. Indeed, Allah is Knowing of that within the breasts."
