Surah Al-Imran, ayah 119

هَٰٓأَنتُمۡ أُوْلَآءِ تُحِبُّونَهُمۡ وَلَا يُحِبُّونَكُمۡ وَتُؤۡمِنُونَ بِٱلۡكِتَٰبِ كُلِّهِۦ وَإِذَا لَقُوكُمۡ قَالُوٓاْ ءَامَنَّا وَإِذَا خَلَوۡاْ عَضُّواْ عَلَيۡكُمُ ٱلۡأَنَامِلَ مِنَ ٱلۡغَيۡظِۚ قُلۡ مُوتُواْ بِغَيۡظِكُمۡۗ إِنَّ ٱللَّهَ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ ١١٩

Hā'antum ulā'i tuhibbūnahum walā yuhibbūnakum watu'minūna bil-kitābi kullihī wa idhā laqūkum qālū āmannā wa idhā khalaw 'addū 'alaykumul-anāmila minal-ghayzi qul mūtū bighayzikum innallāha 'alīmu bidhātis-sudūr

Here you are loving them but they are not loving you, while you believe in the Scripture - all of it.¹⁴⁶ 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, Allāh is Knowing of that within the breasts."
