Al-Hims?. Ibn Al-Qatt?n stated that his reliability was not established by any of the had?th ‘Ulamah and there is another defect in the had?th it self. (1) Besides, the purport of this ‘Athar contradicts the purport of All?h’s ( - عز وجل -) verse that says:

[ ومن أساء فعليها]

‘ and whosoever does evil, it is against his own self’. (2)

[8/ 21] The ruling regarding Suj?d As-Sahwu:

Some Fuqah?’ held that Suj?d As-Sahwu is a recommended act not obligatory one!! The sounder of all the ‘Ulamah’s opinions is, however, that it is a w?jib [an obligation] for the prophet ( - صلى الله عليه وسلم -) ordered muslims to do it [when they forget part of their Sal?t] and he ( - صلى الله عليه وسلم -) himself used to practice it whenever the need exists.

In “Majm?’Al-Fat?w?” (vol. 23/ p. 26), Ibn Taymiyyah ( - رضي الله عنه -) said: ‘It [i.e. Suj?d As-Sahwu] is an obligation for the prophet ( - صلى الله عليه وسلم -) ordered muslims to do it as narrated by Ab? hurairah ( - رضي الله عنه -) to have said: ‘the prophet ( - صلى الله عليه وسلم -) said: ‘whenever a muslim does his Sal?t, Shait?n comes and cast insinuations inside him till the muslim forgets how many Rak’?t he performed. If this happens to any of you, prostrate your self twice while still in the sitting posture [i.e. prior to Tasl?m]’. Ibn Taymiyyah then mentioned another four ah?d?th and added: ‘These five ah?d?th are all authentic ones. They all include the prophet’s ( - صلى الله عليه وسلم -) order for muslims to do Suj?d As-Sahwu [when the need exists].

Once the prophet ( - صلى الله عليه وسلم -) forgot to recite the first Tashahhud, he did Suj?d As-Sahwu before reciting Tasl?m. And once he recited Tasl?m before completing the Sal?t; he performed what he missed of his Sal?t then recited Tasl?m and finally did two Suj?ds. And once he ( - صلى الله عليه وسلم -) performed five Rak’?t instead of four, he did Suj?d As-Sahwu after reciting Tasl?m and even after he talked with his Sah?bah.
