It is narrated from Hazrat Sahl (may Allah be pleased with him) that I heard the Noble Prophet (peace and blessings be upon him) say: I will wait for you at the Pond of Kawthar. Whoever comes there will drink its water, and whoever drinks its water will never feel thirsty again. And some people will come to me whom I will recognize and they will recognize me, but then a barrier will be set up between them and me. Abu Hazim says that when Hazrat Nu'man bin Abi 'Ayyash heard me narrate this hadith, he said: Did you hear Hazrat Sahl (may Allah be pleased with him) say it like this? I replied: Yes! He said: I bear witness regarding Hazrat Abu Sa'id Khudri (may Allah be pleased with him) that I heard him narrate this addition, that the Noble Prophet (peace and blessings be upon him) will say: These are my followers. It will be said: You do not know what deeds they performed after you. I will say: Away with those who changed my religion after me.
