3 – The report shows that the two prostrations of forgetfulness are performed from the sitting position; one is not to stand up first and then go down to prostrate.
4 – It further indicates that following the imam in an unintended mistake does not invalidate the prayer. Nevertheless, once a worshipper realizes the imam’s error he should not continue to follow him—except in the first tashahhud, for in that instance he rises with the imam because the latter only becomes aware of the mistake after he has already stood fully.
5 – The hadith proves that the two prostrations of forgetfulness carry the same legal rulings as the regular prostrations that constitute the core of the prayer.
6 – It also proves that inadvertently or mistakenly turning away from the qiblah does not nullify the prayer.
7 – It establishes that speaking under the assumption that the prayer has ended does not invalidate it, even if the conversation is lengthy.
8 – It provides evidence that, in a case like this, the correct place for the prostrations of forgetfulness is after the final salām.
9 – Abū Saʿīd’s hadith says, “If any one of you is uncertain about his prayer, let him discard the doubt and build upon what he is sure of,” while Ibn Masʿūd’s hadith states, “If any one of you is uncertain about his prayer, let him strive to determine what is correct and then complete it on that basis.” The best reconciliation is that the first hadith concerns a worshipper whose doubt does not allow either possibility to outweigh the other, whereas the second addresses the one for whom one of the two possibilities is predominant; he builds on what his deliberation indicates. Acting on the stronger presumption has already been discussed above.
10 – His statement, “If I forget, then remind me,” proves that the congregants are obliged to alert the imam when he errs in the prayer. Al-Rawḍ al-Murbiʿ and its commentary state: “It is incumbent upon the followers to notify the imam of anything that necessitates the prostrations of forgetfulness, because their prayer is tied to his, and because he, peace and blessings be upon him, commanded them to remind him.”
11 – As for the imam, if two trustworthy worshippers say “subḥān Allāh” to correct him, he must accept their correction—whether they point out an addition or an omission—for the Prophet ﷺ accepted the statement of Abū Bakr and ʿUmar in the incident of Dhū
