Those who were in a hurry left the masjid, and said: "The prayer has been shortened." Among the people were Abu Bakr and 'Umar but they hesitated to ask him for they revere him. Also among the people was a man with long hands who was known as Dhul-Yadain. He said: O Messenger of Allah (ﷺ), did you forget or has the prayer been shortened? He said: I did not forget and the prayer has not been shortened. He said: Is it as Dhul-Yadain says? They said: yes. So he came and prayed what he had missed, then he said the salam, then he said the takbir and prostrated as usual or longer than that. Then he raised his head and said the takbir, and prostrated as usual or longer than that. Then he raised his head and said the takbir.'"

It was narrated from Abu Hurairah that : The Messenger of Allah (ﷺ) finished praying two rak'ahs,and Dhul-Yadain said to him: "Has the prayer been shortened or did you forget, O Messenger of Allah?"

He said: 'One of them happened, O Messenger of Allah (ﷺ).' The Messenger of Allah (ﷺ) turned to the people and said: 'Is Dhul-Yadain speaking the truth?' They said: 'Yes.' So the Messenger of Allah (ﷺ) completed what was left of the prayer, then he prostrated twice when he was sitting after the taslim."

It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) forgot and said the taslim after two rak'ahs.

They said: 'He is speaking the truth, O Messenger of Allah (ﷺ).' So he led them in praying the two rak'ahs that he missed."

Abu Bakr bin Sulaiman bin Abi Hathmah narrated that: It was conveyed to him that the Messenger of Allah (ﷺ) prayed two rak'ahs, and Dhul-Shimalain said something similar to him. (One of the narrators Ibn Shihab said: "Sa'eed bin Al-Musayyab informed me of this hadith from Abu Hurairah."

A man called Al-Khibaq stood up and said: 'Has the prayer been shortened, O Messenger of Allah?' He came out angry, dragging his upper garment and said: 'Is he speaking the truth?' They said: 'Yes.' So he stood and prayed that rak'ah, then he said the salam, then prostrated twice, then he said the salam (again)."

It was narrated from Abu Sa'eed that: The Prophet (ﷺ) said: "If one of you is not sure about his prayer, let him forget about what he is unsure of and complete his prayer on the basis of what he is sure of. When he is sure that he has completed it, let him prostrate twice while he is sitting. Then if he has prayed five (rak'ahs), they (the two prostrations) will make his prayer even-numbered, and if he had prayed four, they will annoy and humiliate the shaitan."
