وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَبْغَضُ النَّاسِ إِلَى الله ثَلَاثَة ملحد فِي الْحرم وميتغ فِي الْإِسْلَام سنة الْجَاهِلِيَّة ومطلب دم امرىء بِغَيْر حق ليهريق دَمه» رَوَاهُ البُخَارِيّ

English translation

Ibn ‘Abbas reported God’s messenger as saying, “The people most hateful to God are of three classes:

he who is heretical in the sacred territory, he who wants to introduce into Islam the sunna of the pre-Islamic period, and he who unjustly demands the death of a Muslim to shed his blood.” Bukhari transmitted it.
