عَنْ عَلِيِّ بْنِ عَبْدِ الرَّحْمَنِ الْمَعَاوِيِّ قَالَ صَلَّيْتُ إِلَى جَنْبِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ فَقَلَبْتُ الْحَصَى، فَقَالَ: لَا تَقْلِبِ الْحَصَى فَإِنَّهُ مِنَ الشَّيْطَانِ وَلَٰكِنْ كَمَا رَأَيْتُ رَسُولَ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَفْعَلُ، كَانَ يُحَرِّكُهُ هَٰكَذَا، قَالَ أَبُو عَبْدِ اللَّهِ يَعْنِي مَسْحَةً
Ali bin Abdur Rahman Muawi says: I prayed next to Sayyiduna Abdullah bin Umar (may Allah be pleased with him) and during the prayer I was turning over pebbles. He said: Do not turn over the pebbles, because doing so is from Satan. However, I saw the Messenger of Allah (peace and blessings be upon him) move them in this way. Imam Abu Abdullah Ahmad said: That is, only once.
