[Machine] The Messenger of Allah ﷺ said, "Arafah is the day on which the Imam (leader) is recognized, and the day of sacrifice is the day on which the Imam offers the sacrifice, and the day of breaking the fast is the day on which the Imam breaks his fast." Muhammad, this (name), is known as "Al-Farisi" and he is from Kufa, a judge from Fars, who has distinguished himself from Sufyan.  

البيهقي:٩٨٢٧أَخْبَرَنَا عَلِيُّ بْنُ أَحْمَدَ بْنِ عَبْدَانَ أنبأ سُلَيْمَانُ بْنُ أَحْمَدَ اللَّخْمِيُّ ثنا عَبْدَانُ بْنُ أَحْمَدَ ثنا يَحْيَى بْنُ حَاتِمٍ الْعَسْكَرِيُّ ثنا مُحَمَّدُ بْنُ إِسْمَاعِيلَ أَبُو إِسْمَاعِيلَ ثنا سُفْيَانُ عَنِ ابْنِ الْمُنْكَدِرِ عَنْ عَائِشَةَ ؓ قَالَتْ

قَالَ رَسُولُ اللهِ ﷺ عَرَفَةُ يَوْمَ يُعَرِّفُ الْإِمَامُ وَالْأَضْحَى يَوْمَ يُضَحِّي الْإِمَامُ وَالْفِطْرُ يَوْمَ يُفْطِرُ الْإِمَامُ مُحَمَّدٌ هَذَا يُعْرَفُ بِالْفَارِسِيِّ وَهُوَ كُوفِيٌّ قَاضِي فَارِسَ تَفَرَّدَ بِهِ عَنْ سُفْيَانَ
