حَدَّثَنَا وَكِيعٌ حَدَّثَنَا سَعِيدُ بْنُ زِيَادٍ عَنْ زِيَادِ بْنِ صُبَيْحٍ الْحَنَفِيِّ قَالَ صَلَّيْتُ إِلَى جَنْبِ ابْنِ عُمَرَ فَوَضَعْتُ يَدِي عَلَى خَاصِرَتِي فَضَرَبَ يَدَيَّ فَلَمَّا صَلَّى قَالَ هَذَا الصَّلْبُ فِي الصَّلَاةِ وَكَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَنْهَى عَنْهُ
مسند امام احمد بن حنبل · Hadith 5836
It was narrated that Ziyaad ibn Subayh al-Hanafi said: I prayed beside Ibn 'Umar and I put my hand on my hip. He struck my hand and when he had finished praying he said: That is making a cross-like shapein prayer and the Messenger o£ Allah (PBUH) used to forbid that.
