It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Some people will come to me at the Pond of Kawthar, and I will see them as they are presented before me, but they will be snatched away from me. I will say, "O Lord! My companions!" It will be said, "You do not know what innovations they introduced after you."
