وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا عَفَّانُ بْنُ مُسْلِمٍ الصَّفَّارُ، حَدَّثَنَا وُهَيْبٌ، قَالَ سَمِعْتُ عَبْدَ الْعَزِيزِ بْنَ صُهَيْبٍ، يُحَدِّثُ قَالَ حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏"‏ لَيَرِدَنَّ عَلَىَّ الْحَوْضَ رِجَالٌ مِمَّنْ صَاحَبَنِي حَتَّى إِذَا رَأَيْتُهُمْ وَرُفِعُوا إِلَىَّ اخْتُلِجُوا دُونِي فَلأَقُولَنَّ أَىْ رَبِّ أُصَيْحَابِي أُصَيْحَابِي ‏.‏ فَلَيُقَالَنَّ لِي إِنَّكَ لاَ تَدْرِي مَا أَحْدَثُوا بَعْدَكَ ‏"‏ ‏.‏

Anas b. Malik reported Allah's Apostle (PBUH) as saying: Some persons from amongst my associates would turn to my Cistern; when I would see them and they would be presented to me, they would be detained in the way while coming to me. I would say: My Lord, they are my companions, they are my companions, and it would be said to me: You don't know what innovations they made after you. Translation Not Available
