For if you do that, every part of your body will prostrate along with you."

الحاكم:٨٢٧ – حَدَّثَنَا أَبُو بَكْرِ بْنُ إِسْحَاقَ الْفَقِيهُ ثنا الْحُسَيْنُ بْنُ مُحَمَّدِ بْنِ زِيَادٍ ثنا عُبَيْدُ اللَّهِ بْنُ سَعْدِ بْنِ إِبْرَاهِيمَ بْنِ سَعْدٍ الزُّهْرِيُّ ثنا عَمِّي ثنا أَبِي عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ قَالَ حَدَّثَنِي مِسْعَرُ بْنُ كِدَامٍ عَنْ آدَمَ بْنِ عَلِيٍّ الْبَكْرِيِّ عَنِ ابْنِ عُمَرَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَبْسُطْ ذِرَاعَيْكَ وَادْعَمْ عَلَى رَاحَتَيْكَ وَتَجَافَ عَنْ ضَبْعَيْكَ فَإِنَّكَ إِذَا فَعَلْتَ ذَلِكَ سَجَدَ كُلُّ عُضْوٍ مِنْكَ مَعَكَ» «قَدِ احْتَجَّ الْبُخَارِيُّ بِآدَمَ بْنِ عَلِيٍّ الْبَكْرِيِّ وَاحْتَجَّ مُسْلِمٌ بِمُحَمَّدِ بْنِ إِسْحَاقَ وَهَذَا صَحِيحٌ وَلَمْ يُخَرِّجَاهُ» صحيح

ذِكْرُ الْأَمْرِ بِالِادِّعَامِ عَلَى الرَّاحَتَيْنِ عِنْدَ السُّجُودِ لِلْمُصَلِّي، إِذِ الْأَعْضَاءُ تَسْجُدُ كَمَا يَسْجُدُ الْوَجْهُ

[Machine] The Messenger of Allah ﷺ said, "Do not extend your arms when you pray, like stretching the wings of a bird, but rather keep them firmly against your sides and let your palms rest on your thighs. Avoid crossing your fingers, for if you do so, every limb of yours will prostrate."  

ابن حبّان:١٩١٤ – أَخْبَرَنَا الْحَسَنُ بْنُ سُفْيَانَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعْدِ بْنِ إِبْرَاهِيمَ الزُّهْرِيُّ حَدَّثَنَا أَبِي وَعَمِّي قَالَا حَدَّثَنَا أَبِي عَنِ ابْنِ إِسْحَاقَ حَدَّثَنِي مِسْعَرُ بْنُ كِدَامٍ عَنْ آدَمَ بْنِ عَلِيٍّ الْبَكْرِيِّ عَنِ ابْنِ عُمَرَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَبْسُطْ ذِرَاعَيْكَ إِذَا صَلَّيْتَ كَبَسْطِ السَّبُعِ وَادَّعِمْ عَلَى رَاحَتَيْكَ وَجَافِ عَنْ ضَبْعَيْكَ فَإِنَّكَ إِذَا فَعَلْتَ ذَلِكَ سَجَدَ كُلُّ عُضْوٍ مِنْكَ»
