Mu'awiyah prayed in front of them, and he stood up during the prayer when he should have sat. The people said tasbih, but he remained standing, then he prostrated twice while he was sitting, after he completed the prayer. Then he sat on the Minbar and said: 'I heard the Messenger of Allah ﷺ say: 'Whoever forgets something in his prayer, let him prostrate twice like this.' (Using translation from Nasāʾī 1260)  

أَنَّهُ صَلَّى أَمَامَهُمْ فَقَامَ فِي الصَّلَاةِ وَعَلَيْهِ جُلُوسٌ فَسَبَّحَ النَّاسُ فَتَمَّ عَلَى قِيَامِهِ ثُمَّ سَجَدَ بِنَا سَجْدَتَيْنِ وَهُوَ جَالِسٌ بَعْدَ أَنْ أَتَمَّ الصَّلَاةَ ثُمَّ قَعَدَ عَلَى الْمِنْبَرِ فَقَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ نَسِيَ مِنْ صَلَاتِهِ شَيْئًا فَلْيَسْجُدْ مِثْلَ هَاتَيْنِ السَّجْدَتَيْنِ  

[Machine] He saw Mu'awiyah leading the people in prayer, so he stood up twice and the people praised Allah. He gestured to them to stand up, and when he finished his prayer, he performed two prostrations before the salutation, and the people prostrated with him. Then he said, "O people, indeed I heard the Messenger of Allah ﷺ saying, 'Whoever has doubt in his prayer, let him perform two prostrations while he is sitting.'"  

أَنَّهُ رَأَى مُعَاوِيَةَ صَلَّى بِالنَّاسِ فَقَامَ فِي الثِّنْتَيْنِ فَسَبَّحَ النَّاسُ فَأَشَارَ إِلَيْهِمْ أَنْ قُومُوا فَلَمَّا فَرَغَ مِنْ صَلَاتِهِ سَجَدَ سَجْدَتَيْنِ قَبْلَ السَّلَامِ وَسَجَدَهُمَا النَّاسُ مَعَهُ ثُمَّ قَالَ يَا أَيُّهَا النَّاسُ إِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ دَاخَلَهُ شَكٌّ فِي صَلَاتِهِ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ»
