حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، قَالَ حَدَّثَنَا وُهَيْبٌ، عَنْ عَبْدِ اللَّهِ بْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، رضى الله عنهما قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ أُمِرْتُ أَنْ أَسْجُدَ عَلَى سَبْعَةِ أَعْظُمٍ عَلَى الْجَبْهَةِ ـ وَأَشَارَ بِيَدِهِ عَلَى أَنْفِهِ ـ وَالْيَدَيْنِ، وَالرُّكْبَتَيْنِ وَأَطْرَافِ الْقَدَمَيْنِ، وَلاَ نَكْفِتَ الثِّيَابَ وَالشَّعَرَ ‏"‏‏.‏
