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