[Machine] Imam Al-Faqih Abu Al-Fath Al-Umari informed us that Abdullah Ibn Al-Sharifi told us that Abu Al-Qasim Al-Baghawi narrated to us from Ali Ibn Muslim who narrated from Abu Dawud who narrated from Shu'bah, who informed us that Thabit said: Anas prayed with us and he stood up when he was supposed to sit, and he sat when he was supposed to stand, and he made two prostrations. He also reported from his companions that they used to do the same.

أَخْبَرَنَا الْإِمَامُ الْفَقِيهُ أَبُو الْفَتْحِ الْعُمَرِيُّ أنبأ عَبْدُ الرَّحْمَنِ الشَّرِيحِيُّ ثنا أَبُو الْقَاسِمِ الْبَغَوِيُّ ثنا عَلِيُّ بْنُ مُسْلِمٍ ثنا أَبُو دَاوُدَ ثنا شُعْبَةُ أنبأ ثَابِتٌ قَالَ صَلَّى بِنَا أَنَسٌ فَقَامَ فِيمَا يَنْبَغِي لَهُ أَنْ يَقْعُدَ أَوْ قَعَدَ فِيمَا يَنْبَغِي لَهُ أَنْ يَقُومَ فَسَجَدَ سَجْدَتَيْنِ وَحَدَّثَ عَنْ أَصْحَابِهِ أَنَّهُمْ كَانُوا يَفْعَلُونَ ذَلِكَ
