It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: (Some people will be prevented from drinking at the Pond of Kawthar.) I will say, "These are my companions." I will be told, "You do not know what innovations they introduced after you." I will say, "Away with those who changed the religion after me."
