[Machine] I was in a gathering with the companions of the Messenger of Allah ﷺ and they were discussing his prayer. Abu Humaid As-Sa'idi said, "I know the prayer of the Messenger of Allah ﷺ better than any of you. It was my habit to observe the Messenger of Allah ﷺ when he stood up for prayer. He would say the takbir, then recite (the Quran). When he bowed, he would say the takbir and place his hands on his knees, separating his fingers. Then he would straighten up his back, not keeping his head bowed nor looking up. When he raised his head, he would stand straight until all his bones returned to their positions. When he prostrated, he would rest on his palms, knees, and the tips of his toes, and he would be at peace while prostrating. When he raised his head, he would be at peace while sitting. When he sat between the two prostrations, he would put his left foot under his buttocks and keep his right foot erect. When he sat in the fourth Rak'ah, he put his left hip on the ground and positioned his feet to one side. Shaikh (Ibn Bazz) said, "In a narration from Abbas bin Sahl from Abu Humaid in this Hadith, he put his hands, knees, and the tips of his toes on the ground when prostrating."  

كُنْتُ فِي مَجْلِسٍ مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ فَتَذَاكَرُوا صَلَاتَهُ فَقَالَ أَبُو حُمَيْدٍ السَّاعِدِيُّ أَنَا أَعْلَمُكُمْ بِصَلَاةِ رَسُولِ اللهِ ﷺ وَكَانَتْ مِنْ هِمَّتِي رَأَيْتُ رَسُولَ اللهِ ﷺ إِذَا قَامَ إِلَى الصَّلَاةِ كَبَّرَ ثُمَّ قَرَأَ فَإِذَا رَكَعَ كَبَّرَ وَوَضَعَ كَفَّيْهِ عَلَى رُكْبَتَيْهِ وَفَرَّجَ بَيْنَ أَصَابِعِهِ ثُمَّ هَصَرَ ظَهْرَهُ غَيْرَ مُقَنِّعٍ رَأْسَهُ وَلَا صَافِحًا بِخَدِّهِ فَإِذَا رَفَعَ قَائِمًا قَامَ حَتَّى يَعُودَ كُلُّ عُضْوٍ إِلَى مَكَانِهِ فَإِذَا سَجَدَ أَمْكَنَ الْأَرْضَ بِكَفَّيْهِ وَرُكْبَتَيْهِ وَصُدُورِ قَدَمَيْهِ ثُمَّ اطْمَأَنَّ سَاجِدًا فَإِذَا رَفَعَ رَأْسَهُ اطْمَأَنَّ جَالِسًا فَإِذَا قَعَدَ فِي الرَّكْعَتَيْنِ قَعَدَ عَلَى بَطْنِ قَدَمِهِ الْيُسْرَى وَنَصَبَ الْيُمْنَى فَإِذَا كَانَتِ الرَّابِعَةُ أَفْضَى بِوَرِكِهِ الْيُسْرَى إِلَى الْأَرْضِ وَأَخْرَجَ قَدَمَيْهِ مِنْ نَاحِيَةٍ وَاحِدَةٍ قَالَ الشَّيْخُ رَحِمَهُ اللهُ وَفِي رِوَايَةِ عَبَّاسِ بْنِ سَهْلٍ عَنْ أَبِي حُمَيْدٍ فِي هَذَا الْحَدِيثِ فَانْتَصَبَ عَلَى كَفَّيْهِ وَرُكْبَتَيْهِ وَصُدُورِ قَدَمَيْهِ فِي السُّجُودِ
