[Machine] The Prophet ﷺ noticed a man praying alone behind the rows, so he commanded him to repeat the prayer like this.  

البيهقي:٥٢٠٧أَخْبَرَنَا أَبُو بَكْرٍ مُحَمَّدُ بْنُ الْحَسَنِ بْنِ فُورَكٍ أنبأ عَبْدُ اللهِ بْنُ جَعْفَرٍ ثنا يُونُسُ بْنُ حَبِيبٍ ثنا أَبُو دَاوُدَ ثنا شُعْبَةُ أَخْبَرَنَا عَمْرُو بْنُ مُرَّةَ قَالَ سَمِعْتُ هِلَالَ بْنَ يِسَافٍ قَالَ سَمِعْتُ عَمْرَو بْنَ رَاشِدٍ عَنْ وَابِصَةَ بْنِ مَعْبَدٍ

أَنَّ النَّبِيَّ ﷺ أَبْصَرَ رَجُلًا يُصَلِّي خَلْفَ الصَّفِّ وَحْدَهُ فَأَمَرَهُ أَنْ يُعِيدَ الصَّلَاةَ هَكَذَا  

رَوَاهُ عَمْرُو بْنُ مُرَّةَ وَخَالَفَهُ حُصَيْنُ بْنُ عَبْدِ الرَّحْمَنِ فَرَوَاهُ عَنْ هِلَالِ بْنِ يِسَافٍ
