[Machine] I heard Abu Humaid Al-Sa'idi discussing ten of the companions of the Prophet ﷺ , one of whom was Abu Qatadah. He mentioned a hadith about the description of the Prophet's prayer ﷺ , saying that after sujood, he would lean on the ground and separate his hands from his sides, then he would raise his head and bend his left leg, sitting on it.  

سَمِعْتُ أَبَا حُمَيْدٍ السَّاعِدِيَّ فِي عَشَرَةٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ فِيهِمْ أَبُو قَتَادَةَ فَذَكَرَ الْحَدِيثَ فِي صِفَةِ صَلَاةِ رَسُولِ اللهِ ﷺ قَالَ فِيهِ ثُمَّ يَهْوِي سَاجِدًا إِلَى الْأَرْضِ فَيُجَافِي يَدَيْهِ عَنْ جَنْبَيْهِ ثُمَّ يَرْفَعُ رَأْسَهُ فَيَثْنِي رِجْلَهُ الْيُسْرَى فَيَقْعُدُ عَلَيْهَا  

[Machine] He was in a gathering where his father was present, and he was one of the companions of the Prophet ﷺ . In the gathering were Abu Huraira, Abu Usaid, and Abu Humaid Al-Saadi, who were from the Ansar. They were discussing prayer, and Abu Humaid said, "I know the prayer of the Messenger of Allah ﷺ ." Then he mentioned the narration in which the Messenger of Allah ﷺ said, "Allahu Akbar," and he prostrated, with his palms, knees, and the tops of his feet touching the ground, while he was in prostration. Then he said, "Allahu Akbar," and he sat up, placing one of his legs on top of the other, and he raised his other foot. Then he said, "Allahu Akbar," and he prostrated again, and he mentioned the narration. It has been reported in the chain of narrators that Isa bin Abdullah heard it from Abbas bin Sahl, who has attended the prayer with Abu Humaid and Abu Usaid, among others.  

أَنَّهُ كَانَ فِي مَجْلِسٍ فِيهِ أَبُوهُ وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ وَكَانَ فِي الْمَجْلِسِ أَبُو هُرَيْرَةَ وَأَبُو أُسَيْدٍ وَأَبُو حُمَيْدٍ السَّاعِدِيُّ مِنَ الْأَنْصَارِ وَأَنَّهُمْ تَذَاكَرُوا الصَّلَاةَ فَقَالَ أَبُو حُمَيْدٍ أَنَا أَعْلَمُكُمْ بِصَلَاةِ رَسُولِ اللهِ ﷺ فَذَكَرَ الْحَدِيثَ قَالَ فِيهِ ثُمَّ قَالَ اللهُ أَكْبَرُ فَسَجَدَ وَانْتَصَبَ عَلَى كَفَّيْهِ وَرُكْبَتَيْهِ وَصُدُورِ قَدَمَيْهِ وَهُوَ سَاجِدٌ ثُمَّ كَبَّرَ فَجَلَسَ فَتَوَرَّكَ إِحْدَى رِجْلَيْهِ وَنَصَبَ قَدَمَهُ الْأُخْرَى ثُمَّ كَبَّرَ وَسَجَدَ وَذَكَرَ الْحَدِيثَ وَقَدْ قِيلَ فِي إِسْنَادِهِ عَنْ عِيسَى بْنِ عَبْدِ اللهِ سَمِعَهُ مِنْ عَبَّاسِ بْنِ سَهْلٍ أَنَّهُ حَضَرَ أَبَا حُمَيْدٍ وَأَبَا أُسَيْدٍ وَرِجَالًا مِنْهُمْ فِي الصَّلَاةِ
