حَدَّثَنَا قُتَيْبَةُ ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ ، عَنْ عَمْرِو بْنِ دِينَارٍ ، عَنْ طَاوُسٍ ، عَنِ ابْنِ عَبَّاسٍ ، قَالَ أُمِرَ النَّبِيُّ صلى الله عليه وسلم أَنْ يَسْجُدَ عَلَى سَبْعَةِ أَعْظُمٍ وَلاَ يَكُفَّ شَعْرَهُ وَلاَ ثِيَابَهُ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
"The Prophet ordered that one prostrate on seven bones and that he not gather his hair nor his garment."
