[Machine] The Messenger of Allah ﷺ prayed with us a prayer, sometimes he added to it and sometimes he deducted from it. So, some of them said, "Did he innovate in the prayer?" He said, "No, nothing was added to it that I have not informed you about, and if something new was added, I would have informed you. But I am a human being, I forget, so if I forget, remind me." So, he completed the remaining part of his prayer, then he performed the two prostrations of forgetfulness, then he said, "If anyone of you prays and is unsure whether they added something or deducted from it, then let them choose the correct option from that, then let them perform two prostrations while sitting."  

صَلَّى بِنَا رَسُولُ اللهِ ﷺ صَلَاةً إِمَّا زَادَ فِيهَا وَإِمَّا نَقَصَ فَقَالَ لَهُ بَعْضُهُمْ أَحَدَثَ فِي الصَّلَاةِ؟ قَالَ «مَا حَدَثَ فِيهَا شَيْءٌ وَلَوْ أُحْدِثَ فِيهَا لَحَدَّثْتُكُمْ وَلَكِنِّي بَشَرٌ أَنْسَى فَإِذَا نَسِيتُ فَأَذْكِرُونِي» فَصَلَّى مَا بَقِيَ مِنْ صَلَاتِهِ ثُمَّ سَجَدَ سَجْدَتَيِ السَّهْوِ ثُمَّ قَالَ «إِذَا صَلَّى أَحَدُكُمْ فَلَمْ يَدْرِ أَزَادَ أَمْ نَقَصَ فَلْيَتَوَخَّ الصَّوَابَ مِنْ ذَلِكَ ثُمَّ لِيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ»
