'The Messenger of Allah ﷺ did not prostrate that day either before the salam or after."
أَنَّهُ قَالَ لَمْ يَسْجُدْ رَسُولُ اللَّهِ ﷺ يَوْمَئِذٍ قَبْلَ السَّلاَمِ وَلاَ بَعْدَهُ
'The Messenger of Allah ﷺ did not prostrate that day either before the salam or after."
أَنَّهُ قَالَ لَمْ يَسْجُدْ رَسُولُ اللَّهِ ﷺ يَوْمَئِذٍ قَبْلَ السَّلاَمِ وَلاَ بَعْدَهُ
[Machine] On the authority of the Prophet ﷺ, he said, "For every mistake, two prostrations (Sajdah) should be performed after the concluding salutation (Salam)."
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لِكُلِّ سَهْوٍ سَجْدَتَانِ بَعْدَ مَا يُسَلِّمُ
'The Messenger of Allah ﷺ did not prostrate that day either before the salam or after." (Using translation from Nasāʾī 1232)
أَنَّهُ «لَمْ يَسْجُدْ رَسُولُ اللهِ ﷺ يَوْمَئِذٍ قَبْلَ السَّلَامِ وَلَا بَعْدَهُ»
