My Lord, they are my friends, they are my friends, and it would be said: You don't know what innovations they made after you. (Using translation from Muslim 2297a)
قَالَ رَسُولُ اللهِ ﷺ أَنَا فَرَطُكُمْ عَلَى الْحَوْضِ وَلَأُنَازَعَنَّ أَقْوَامًا ثُمَّ لَأُغْلَبَنَّ عَلَيْهِمْ فَأَقُولُ يَا رَبِّ أَصْحَابِي فَيُقَالُ إِنَّكَ لَا تَدْرِي مَا أَحْدَثُوا بَعْدَكَ
