(Second chain) The Noble Prophet (peace and blessings be upon him and his family) led the people in five rak‘ahs, and after saying salam, he turned and sat facing them. Some people began to speak secretly among themselves. Then they said, "O Messenger of Allah! You have led five rak‘ahs." The Prophet (peace and blessings be upon him and his family) turned back, performed two prostrations, said salam, and said: "I am only a human being; just as you forget, I also forget."
