‘Afw ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, said, “The Jews split into seventy-one sects, one of them is in Paradise and seventy are in the Hellfire. The Christians split into seventy-two sects, seventy-one are in the Hellfire and one of them is in Paradise. By the One in whose hand is the soul of Muhammad, my nation will split into seventy-three sects, one of them is in Paradise and seventy-two are in the Hellfire.” It was said, “O Messenger of Allah, who are the ones in Paradise?” The Prophet said, “The united community.”

عَنْ عَوْفِ بْنِ مَالِكٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ افْتَرَقَتْ الْيَهُودُ عَلَى إِحْدَى وَسَبْعِينَ فِرْقَةً فَوَاحِدَةٌ فِي الْجَنَّةِ وَسَبْعُونَ فِي النَّارِ وَافْتَرَقَتْ النَّصَارَى عَلَى ثِنْتَيْنِ وَسَبْعِينَ فِرْقَةً فَإِحْدَى وَسَبْعُونَ فِي النَّارِ وَوَاحِدَةٌ فِي الْجَنَّةِ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَتَفْتَرِقَنَّ أُمَّتِي عَلَى ثَلَاثٍ وَسَبْعِينَ فِرْقَةً وَاحِدَةٌ فِي الْجَنَّةِ وَثِنْتَانِ وَسَبْعُونَ فِي النَّارِ قِيلَ يَا رَسُولَ اللَّهِ مَنْ هُمْ قَالَ الْجَمَاعَةُ
