Sahih Ibn Khuzaymah

Sayyiduna Abu Hurairah رضي الله عنه narrates from the Prophet صلى الله عليه وسلم a hadith similar to the one mentioned above. That is, "The Prophet صلى الله عليه وسلم performed two prostrations of forgetfulness on the day when, after concluding the prayer with salam, Dhu’l-Yadayn came to him صلى الله عليه وسلم (and informed him about the deficiency in the prayer)." Imam Abu Bakr رحمه الله says that this narration of Ibn Sirin from Sayyiduna Abu Hurairah رضي الله عنه indicates the heedlessness of the person who thinks that this incident occurred before the prohibition of speaking during prayer by the Prophet صلى الله عليه وسلم. And whoever possesses scholarly understanding and has reflected upon the statements of the Prophet صلى الله عليه وسلم and the words of the narrators of this hadith, he knows that saying such a thing is based on ignorance. In the narration of Ibn Sirin from Sayyiduna Abu Hurairah رضي الله عنه, these words are present: "The Messenger of Allah صلى الله عليه وسلم led us in prayer." Similarly, Imam Malik bin Anas رحمه الله has narrated this with his chain from Abu Sufyan, the freed slave of Bani Abi Ahmad, from Sayyiduna Abu Hurairah رضي الله عنه. In it, instead of "salla bina," the words "salla lana" are used (the meaning is the same, that the Messenger of Allah صلى الله عليه وسلم led us in prayer).
