[Machine] The Prophet ﷺ prayed the morning prayer in Mecca and began reciting Surah Al-Mu'minun, until when the mention of Moses and Aaron or the mention of Jesus came, Muhammad ibn 'Abbad started to doubt and they disagreed about it. The Prophet ﷺ then took a small mat, and said a prostration prayer. Ibn As-Sa'ib was present as well.  

صَلَّى النَّبِيُّ ﷺ بِمَكَّةَ الصُّبْحَ فَاسْتَفْتَحَ سُورَةَ الْمُؤْمِنِينَ حَتَّى إِذَا جَاءَ ذِكْرُ مُوسَى وَهَارُونَ أَوْ ذِكْرُ عِيسَى مُحَمَّدُ بْنُ عَبَّادٍ يَشُكُّ وَاخْتَلَفُوا عَلَيْهِ أَخَذْتِ النَّبِيَّ ﷺ سَعْلَةٌ قَالَ فَرَكَعَ وَابْنُ السَّائِبِ حَاضِرٌ كَذَلِكَ  

we were commanded to recite Fatihat al-kitab and whatever was convenient (from the Qur’an during the prayer). (Using translation from Abū Dāʾūd 818)   

أَمَرَنَا رَسُولُ اللهِ ﷺ أَنْ نَقْرَأَ بِفَاتِحَةِ الْكِتَابِ وَبِمَا تَيَسَّرَ
