[Machine] "The Prophet ﷺ prayed two Rak'ahs in which he did not exceed the recitation of Al-Fatiha. Abu Saad Al-Malini informed us that Abu Ahmad ibn Adi reported to us from Ibrahim ibn Muhammad ibn Isa, who reported from Abu Musa Muhammad ibn Al-Muthanna, who reported from Abu Bahra Al-Bakrawi, who reported from Hanzala As-Sadusi. He mentioned and it was narrated from Ibn Abbas regarding his statement on the permissibility of limiting the recitation to only Al-Fatiha."  

البيهقي:٢٤٧١وَرَوَاهُ غَيْرُهُمَا عَنْ حَنْظَلَةَ ثنا شَهْرُ بْنُ حَوْشَبٍ عَنِ ابْنِ عَبَّاسٍ

أَنَّ النَّبِيَّ ﷺ صَلَّى رَكْعَتَيْنِ لَمْ يَزِدْ فِيهِمَا عَلَى فَاتِحَةِ الْكِتَابِ أَخْبَرَنَا أَبُو سَعْدٍ الْمَالِينِيُّ أنبأ أَبُو أَحْمَدَ بْنُ عَدِيٍّ ثنا إِبْرَاهِيمُ بْنُ مُحَمَّدِ بْنِ عِيسَى ثنا أَبُو مُوسَى مُحَمَّدُ بْنُ الْمُثَنَّى ثنا أَبُو بَحْرٍ الْبَكْرَاوِيُّ ثنا حَنْظَلَةُ السَّدُوسِيُّ فَذَكَرَهُ وَرُوِيَ عَنِ ابْنِ عَبَّاسٍ مِنْ قَوْلِهِ فِي جَوَازِ الِاقْتِصَارِ عَلَى فَاتِحَةِ الْكِتَابِ
