It was narrated from Ibn ‘Umar that the Messenger of Allah (ﷺ) forgot and said the Taslim after two Rak’ah. A man who was called Dhul-Yadain said to him: ‘O Messenger of Allah, has the prayer been shortened or did you forget?’ He said: ‘It has not been shortened and I did not forget.’ He said: ‘But you prayed two Rak’ah.’ He said: ‘Is what Dhul-Yadain says true?’ They said: ‘Yes.’ So he went forward and performed two Rak’ah and said the Salam, then he prostrated twice for prostrations of forgetfulness.

It was narrated that Abu Hurairah said: “The Messenger of Allah (ﷺ) led us in one of the afternoon prayers, and he prayed two Rak’ah, then he said the Salam. Then he stood up and went to a piece of wood in the mosque, and leaned against it. Those who were in a hurry left the mosque, saying that the prayer had been shortened. Among the people were Abu Bakr and ‘Umar, but they dared not say anything. Among the people there was also a man with long hands who was called Dhul- Yadain. He said: ‘O Messenger of Allah, has the prayer been shortened or did you forget?’ He said: ‘It has not been shortened and I did not forget.’ He said: ‘But you prayed two Rak’ah.’ He said: ‘Is what Dhul- Yadain says true?’ They said: ‘Yes.’ So he went forward and performed two Rak’ah and said the Salam, then he prostrated twice, and then he said the Salam again.”

It was narrated that ‘Imran bin Husain said: “The Messenger of Allah (ﷺ) said the Salam after three Rak’ah for ‘Asr, then he stood up and went into the apartment. Khirbaq, a man with big hands, stood up and called out: ‘O Messenger of Allah! Has the prayer been shortened?’ He came out angrily, dragging his lower garment, and asked about it, and was told (what had happened). So he performed the Rak’ah that he had omitted, then he said the Salam, then he prostrated twice and said the Salam again.”
