[Machine] The Messenger of Allah ﷺ went out to perform the Fajr prayer, and Bilal was with him. He led the prayer and passed by me, saying, "You should pray four (rak'ahs) for Fajr." Sheikh Abu Bakr ibn Ishaq narrated that I am Al-Hasan ibn Ali ibn Ziyad, reporting from Abu Hummah, who reported from Abu Qura, who reported from Ibn Juraij and Sufyan Ath-Thawri, who reported from Ja'far ibn Muhammad. They mentioned the hadith in a similar manner.  

خَرَجَ رَسُولُ اللَّهِ ﷺ إِلَى صَلَاةِ الصُّبْحِ وَمَعَهُ بِلَالٌ فَأَقَامَ الصَّلَاةَ فَمَرَّ بِي وَقَالَ تُصَلِّي الصُّبْحَ أَرْبَعًا أَنْبَأَ الشَّيْخُ أَبُو بَكْرِ بْنُ إِسْحَاقَ أَنَا الْحَسَنُ بْنُ عَلِيِّ بْنِ زِيَادٍ ثَنَا أَبُو حُمَةَ ثَنَا أَبُو قُرَّةَ عَنِ ابْنِ جُرَيْجٍ وَسُفْيَانُ الثَّوْرِيُّ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ فَذَكَرَ الْحَدِيثَ بِنَحْوِهِ
