Arabic hadith text
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ مُغِيرَةَ، عَنْ أَبِي وَائِلٍ، قَالَ قَالَ عَبْدُ اللَّهِ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏أَنَا فَرَطُكُمْ عَلَى الْحَوْضِ، لَيُرْفَعَنَّ إِلَىَّ رِجَالٌ مِنْكُمْ حَتَّى إِذَا أَهْوَيْتُ لأُنَاوِلَهُمُ اخْتُلِجُوا دُونِي فَأَقُولُ أَىْ رَبِّ أَصْحَابِي‏.‏ يَقُولُ لاَ تَدْرِي مَا أَحْدَثُوا بَعْدَكَ ‏"
Translation
Narrated `Abdullah

The Prophet (ﷺ) said, "I am your predecessor at the Lake-Fount (Kauthar) and some men amongst you will be brought to me, and when I will try to hand them some water, they will be pulled away from me by force whereupon I will say, 'O Lord, my companions!' Then the Almighty will say, 'You do not know what they did after you left, they introduced new things into the religion after you.'"
