[Machine] That the Messenger of Allah ﷺ said, "When the prayer is established, there is no prayer except the obligatory prayer, except for the two Rak'ahs of Fajr." Abu Bakr ibn al-Harith informed Abu Muhammad ibn Hayyan, who narrated from Muhammad ibn Ibrahim ibn Dawud, who narrated from Abu Amr al-Halabi al-Susi, who narrated from Hajjaj ibn Nusayr. This addition has no basis. Hajjaj ibn Nusayr and Abbad ibn Kathir are both weak narrators. It has been said about Hajjaj, by way of his chain of narration from Mujahid, that he replaced Ata', but there is no basis for this. And we have narrated from Umar ibn al-Khattab that when he saw a man praying and he heard the call to prayer, he hit him.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا أُقِيمَتِ الصَّلَاةُ فَلَا صَلَاةَ إِلَّا الْمَكْتُوبَةَ إِلَّا رَكْعَتَيِ الصُّبْحِ أنبأ أَبُو بَكْرِ بْنُ الْحَارِثِ أنبأ أَبُو مُحَمَّدِ بْنُ حَيَّانَ ثنا مُحَمَّدُ بْنُ إِبْرَاهِيمَ بْنِ دَاوُدَ ثنا أَبُو عَمْرٍو الْحَلَبِيُّ السُّوسِيُّ ثنا حَجَّاجُ بْنُ نُصَيْرٍ فَذَكَرَهُ وَهَذِهِ الزِّيَادَةُ لَا أَصْلَ لَهَا وَحَجَّاجُ بْنُ نُصَيْرٍ وَعَبَّادُ بْنُ كَثِيرٍ ضَعِيفَانِ وَقَدْ قِيلَ عَنْ حَجَّاجٍ بِإِسْنَادِهِ عَنْ مُجَاهِدٍ بَدَلَ عَطَاءٍ وَلَيْسَ بِشَيْءٍ وَرُوِّينَا عَنْ عُمَرَ بْنِ الْخَطَّابِ ؓ أَنَّهُ كَانَ إِذَا رَأَى رَجُلًا يُصَلِّي وَهُوَ يَسْمَعُ الْإِقَامَةَ ضَرَبَهُ
