"I prayed beside Ibn Umar and I turned over the pebbles. Ibn Umar said to me: 'Do not turn over the pebbles, for turning over the pebbles comes from Shaitan. Do what I saw the Messenger of Allah ﷺ do.' I said: 'What did you see the Messenger of Allah ﷺ do?' He said; 'This'- and he held his right foot upright and lay his left foot on the ground, and placed his right hand on his right thigh and his left hand on his left thigh, and pointed with his forefinger."

الكبرى للنسائي:١١٩٠ – أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ حَدَّثَنَا سُفْيَانُ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ مُسْلِمِ بْنِ أَبِي مَرْيَمَ شَيْخٌ مِنْ أَهْلِ الْمَدِينَةِ ثُمَّ لَقِيتُ الشَّيْخَ فَقَالَ سَمِعْتُ عَلِيَّ بْنَ عَبْدِ الرَّحْمَنِ يَقُولُ صَلَّيْتُ إِلَى جَنْبِ ابْنِ عُمَرَ فَقَلَّبْتُ الْحَصَى فَقَالَ

لِي ابْنُ عُمَرَ لَا تُقَلِّبِ الْحَصَى فَإِنَّ تَقْلِيبَ الْحَصَى مِنَ الشَّيْطَانِ وَافْعَلْ كَمَا رَأَيْتُ رَسُولَ اللهِ ﷺ يَفْعَلُ قُلْتُ كَيْفَ رَأَيْتَ رَسُولَ اللهِ ﷺ يَفْعَلُ قَالَ هَكَذَا «وَنَصَبَ الْيُمْنَى وَأَضْجَعَ الْيُسْرَى وَوَضَعَ يَدَهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى وَيَدَهُ الْيُسْرَى عَلَى فَخِذِهِ الْيُسْرَى وَأَشَارَ بِالسَّبَّابَةِ»
