Narrated Abu Hurairah: When the Prophet ﷺ finished two rak'ahs of an obligatory prayer, a man asked him: Messenger of Allah, has the prayer been shortened, or have you forgotten? he replied: I did not do all that. The people said: Messenger of Allah, you did that. Therefore, he offered another two rak'ahs or prayer and did not make two prostrations due to forgetfulness. Abu Dawud said: This tradition has also been narrated by Dawud al-Hussain from Abu Sufyan, freed slave of Ibn Abi Ahmad on the authority of Abu Hurairah from the Prophet ﷺ. This version goes: He then made two prostrations while he was sitting after the salutation.

In this, the words "«ولم يسجد سجدتي السهو» 'did not perform the two prostrations of forgetfulness (sujud as-sahw)'" are irregular (shaadh). (Shaykh al-Albani)
