I heard Allah's Apostle ﷺ as saying: I shall go to the Cistern before you and he who comes would drink and he who drinks would never feel thirsty, and there would come to me people whom I would know and who would know me. Then there would be intervention between me and them. Abu Hazim said that Nu'man b. Abu 'Ayyash heard it and I narrated to them this hadith, and said: Is it this that you heard Sahl saying? He said: Yes, and I bear witness to the fact that I heard it from Abu Sa'id Khudri also, but he made this addition that he (the Holy Prophet) would say: They are my followers, and it would be said to him: You do not know what they did after you and I will say to them: Woe to him who changes (his religion) after me.  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ أَنَا فَرَطُكُمْ عَلَى الْحَوْضِ مَنْ وَرَدَ شَرِبَ وَمَنْ شَرِبَ لَمْ يَظْمَأْ أَبَدًا وَلَيَرِدَنَّ عَلَىَّ أَقْوَامٌ أَعْرِفُهُمْ وَيَعْرِفُونِي ثُمَّ يُحَالُ بَيْنِي وَبَيْنَهُمْ قَالَ أَبُو حَازِمٍ فَسَمِعَ النُّعْمَانُ بْنُ أَبِي عَيَّاشٍ وَأَنَا أُحَدِّثُهُمْ هَذَا الْحَدِيثَ فَقَالَ هَكَذَا سَمِعْتَ سَهْلاً يَقُولُ قَالَ فَقُلْتُ نَعَمْ قَالَ وَأَنَا أَشْهَدُ عَلَى أَبِي سَعِيدٍ الْخُدْرِيِّ لَسَمِعْتُهُ يَزِيدُ فَيَقُولُ إِنَّهُمْ مِنِّي فَيُقَالُ إِنَّكَ لاَ تَدْرِي مَا عَمِلُوا بَعْدَكَ فَأَقُولُ سُحْقًا سُحْقًا لِمَنْ بَدَّلَ بَعْدِي

(Using translation from Muslim 2290)   

قَالَ رَسُولُ اللهِ ﷺ أَنَا فَرَطُكُمْ عَلَى الْحَوْضِ مَنْ وَرَدَ عَلَيَّ شَرِبَ وَمَنْ شَرِبَ لَمْ يَظْمَأْ أَبَدًا أَبْصَرْتُ أَنْ لَا يَرِدَ عَلَيَّ أَقْوَامٌ أَعْرِفُهُمْ وَيَعْرِفُونَنِي ثُمَّ يُحَالُ بَيْنِي وَبَيْنَهُمْ قَالَ فَسَمِعَنِي النُّعْمَانُ بْنُ أَبِي عَيَّاشٍ أُحَدِّثُ بِهِ فَقَالَ وَأَشْهَدُ أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ يَزِيدُ فِيهِ فَيَقُولُ وَأَقُولُ إِنَّهُمْ أُمَّتِي أَوْ مِنِّي فَيُقَالُ إِنَّكَ لَا تَدْرِي مَا أَحْدَثُوا بَعْدَكَ أَوْ مَا بَدَّلُوا بَعْدَكَ فَأَقُولُ سُحْقًا سُحْقًا لِمَنْ بَدَّلَ بَعْدِي  

"أَنا فرطكم على الحوض، من وردَ يشرَبُ، ومن يشرب لم يظمأ أَبدًا، وليرِدَنَّ علىَّ أَقوامٌ أَعرفهم ويعرفونى ثمَّ يحالُ بينى وبينهم، فأَقول: إِنهم منِّى. فيُقَالُ: إِنَّك لا تدرى ما عملوا بعدك. فأَقول: سحقًا لمن بدَّلَ بعدى" .  

"إِنِّى فرطُكُم على الْحَوْضِ، مَنْ مَرَّ علىَّ شرِبَ، وَمَنْ شرِبَ لمْ يَظْمأْ أَبدًا، وليردنَّ علىّ أَقوامٌ أَعْرِفُهم وَيَعْرِفونى ثُمَّ يحالُ بَيْنِى وبيْنَهُمْ، فأَقولُ: إِنَّهُمْ مِنِّى فيقالُ: إِنَّك لا تَدْرِى ما أَحدثُوا بعْدَكَ فأَقُولُ سُحْقًا سُحقًا لِمَنْ بَدَّلَ بَعْدِى".
