Messenger of Allah ﷺ passed by a man praying two rakʿat after the Iqama (had been pronounced). When Messenger of Allah ﷺ completed the prayer, the people gathered around him (the Prophet) or that man and Messenger of Allah ﷺ said to him (protesting), Are there four rakʿat in Fajr prayer? Are there four rakʿat in Fajr prayer?"  

أَنَّ رَسُولَ اللَّهِ ﷺ رَأَى رَجُلاً وَقَدْ أُقِيمَتِ الصَّلاَةُ يُصَلِّي رَكْعَتَيْنِ فَلَمَّا انْصَرَفَ رَسُولُ اللَّهِ ﷺ لاَثَ بِهِ النَّاسُ وَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ: «الصُّبْحَ أَرْبَعًا؟ الصُّبْحَ أَرْبَعًا؟»  

[Machine] The morning prayer was established and a man stood up to perform the two units of prayer. The Messenger of Allah ﷺ pulled his garment and said, "Are you praying the morning prayer as four units?"  

أُقِيمَتْ صَلاةُ الصُّبْحِ فَقَامَ رَجُلٌ يُصَلِّي الرَّكْعَتَيْنِ فَجَذَبَ رَسُولُ اللهِ ﷺ بِثَوْبِهِ فَقَالَ أَتُصَلِّي الصُّبْحَ أَرْبَعًا؟  

[Machine] A man entered the mosque while the prayer had already started, so he prayed the two units of the Fajr prayer. When the Messenger of Allah ﷺ finished, the man asked if the morning prayer is four units.  

أَنَّ رَجُلًا دَخَلَ الْمَسْجِدَ وَقَدْ أُقِيمَتِ الصَّلَاةُ فَصَلَّى رَكْعَتَيِ الْفَجْرِ فَلَمَّا قَضَى رَسُولُ اللهِ ﷺ لَاثَ بِهِ النَّاسُ فَقَالَ الصُّبْحُ أَرْبَعًا؟  

[Machine] The translation is: The prayer was established, and the Prophet ﷺ saw a man praying two units of prayer. When the Prophet ﷺ finished his prayer, the people approached him and said: "Do you pray four units for the Fajr prayer?"  

أُقِيمَتِ الصَّلَاةُ فَرَأَى النَّبِيُّ ﷺ رَجُلًا يُصَلِّي الرَّكْعَتَيْنِ فَلَمَّا قَضَى النَّبِيُّ ﷺ صَلَاتَهُ لَاثَ بِهِ النَّاسُ فَقَالَ لَهُ النَّبِيُّ ﷺ «أَتُصَلِّي الصُّبْحَ أَرْبَعًا؟»
