Sunan Ibn Majah, Book 36, Hadith 68 (In-Book) ⓘ
It was narrated from Anas bin Malik that the Messenger of Allah said: ‘The Children of Israel split into seventy-one sects, and my nation will split into seventy-two, all of which will be in Hell apart from one, which is the main body.”
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ، حَدَّثَنَا أَبُو عَمْرٍو، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِنَّ بَنِي إِسْرَائِيلَ افْتَرَقَتْ عَلَى إِحْدَى وَسَبْعِينَ فِرْقَةً وَإِنَّ أُمَّتِي سَتَفْتَرِقُ عَلَى ثِنْتَيْنِ وَسَبْعِينَ فِرْقَةً كُلُّهَا فِي النَّارِ إِلاَّ وَاحِدَةً وَهِيَ الْجَمَاعَةُ " .
