[1287] 96 - (...) It was narrated that 'Abdullāh said: "We offered prayers with the Messenger of Allāh ﷺ and he either added or omitted something. We said: 'O Messenger of Allāh, has something (new) been introduced into the prayer?' He said: 'No.' We told him what he had done and he said: 'If a man adds or omits something, let him prostrate twice.' Then he prostrated twice."
