Musnad Abi Ya'la 4184 — he said: I no longer recognise

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he said: "I no longer recognise (in its original form) anything that existed in the blessed time of the Messenger of Allah (peace and blessings be upon him)." It was said to him: "O Abu Hamzah! What about the prayer? (Has it also changed?)" He said: "Have you not done in the prayer what you well know?" (That is, have you not made those changes and shortcomings in its times and performance that are evident to you?)
