Sahl (b. Sad) reported: I heard Allahs 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 Numan bin 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 Said 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.
