Qur'an 3:119

هَـٰٓأَنتُمْ أُو۟لَآءِ تُحِبُّونَهُمْ وَلَا يُحِبُّونَكُمْ وَتُؤْمِنُونَ بِٱلْكِتَـٰبِ كُلِّهِۦ وَإِذَا لَقُوكُمْ قَالُوٓا۟ ءَامَنَّا وَإِذَا خَلَوْا۟ عَضُّوا۟ عَلَيْكُمُ ٱلْأَنَامِلَ مِنَ ٱلْغَيْظِ ۚ قُلْ مُوتُوا۟ بِغَيْظِكُمْ ۗ إِنَّ ٱللَّهَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ

Lo! ye are those who love them though they love you not, and ye believe in all the Scripture. When they fall in with you they say: We believe; but when they go apart they bite their finger-tips at you, for rage. Say: Perish in your rage! Lo! Allah is Aware of what is hidden in (your) breasts.
