Caution: Translations of Quran and Ḥadīth may lead to possible misapplications and misinterpretations. This site is intended for students of sacred knowledge that are proficient in comprehending classical Arabic and have a strong foundation in Islamic sciences. Also note that religious injunctions rely on several aspects beyond what one may glean through reading individual aḥādīth.
quran:3:119

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."  

Lo (hā, ‘lo!’, is for calling attention ˹to something˺), there you are, O believers, you love them, on account of their kinship and their ˹pretence of˺ friendship towards you, but they love you not, since they oppose you in religion; you believe in the Book, all of it, that is to say, in the Books, all of them, but they do not believe in your Book, and when they meet you they say, ‘We believe,’ but when they are alone, they bite at you their fingertips, in rage, in extreme fury at what they see of your mutual affection: the biting of the fingertips is used to figuratively express the severity of rage, even if there be no biting involved. Say: ‘Perish in your rage, that is, be this way until the end of your lives, for you shall not see what will please you; God knows what is in the breasts’, what is in the hearts, including that which these conceal.
القرآن:٣:١١٩

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  

{ها} للتنبيه {أنتم} يا {أولاء} المؤمنون {تحبونهم} لقرابتهم منكم وصداقتهم {ولا يحبونكم} لمخالفتهم لكم في الدين {وتؤمنون بالكتاب كله} أي بالكتب كلها ولا يؤمنون بكتابكم {وإذا لقوكم قالوا آمنا وإذا خلوا عضوا عليكم الأنامل} أطراف الأصابع {من الغيظ} شدة الغضب لما يرون من ائتلافكم ويعبر عن شدة الغضب بِعَضِّ الأنامل مجازا وإن لم يكن ثم عض {قل موتوا بغيظم} أي ابقوا عليه إلى الموت فلن تروا ما يسركم {إن الله عليم بذات الصدور} بما في القلوب ومنه ما يضمره هؤلاء.
