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)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ أَنَا فَرَطُكُمْ عَلَى الْحَوْضِ وَسَأُنَازَعُ رِجَالًا فَأُغْلَبُ عَلَيْهِمْ فَلَأَقُولَنَّ رَبِّ أُصَيْحَابِي أُصَيْحَابِي فَلَيُقَالَنَّ لِي إِنَّكَ لَا تَدْرِي مَا أَحْدَثُوا بَعْدَكَ
