 3:119

هَا أَنْتُمْ أُولَاءِ تُحِبُّونَهُمْ وَلَا يُحِبُّونَكُمْ وَتُؤْمِنُونَ بِالْكِتَابِ كُلِّهِ وَإِذَا لَقُوكُمْ قَالُوا آمَنَّا وَإِذَا خَلَوْا عَضُّوا عَلَيْكُمُ الْأَنَامِلَ مِنَ الْغَيْظِ ۚ قُلْ مُوتُوا بِغَيْظِكُمْ ۗ إِنَّ اللَّهَ عَلِيمٌ بِذَاتِ الصُّدُورِ ﴿١١٩﴾

119. Here you are! You love them, but they do not love you, and you believe in the entire Scripture. And when they meet you, they say, “We believe.” But when they are alone, they bite their fingers at you in rage. Say, “Die in your rage; Allah knows what the hearts contain.”
