حَدَّثَنَا قَبِيصَةُ قَالَ حَدَّثَنَا سُفْيَانُ عَنْ عَمْرِو بْنِ دِينَارٍ عَنْ طَاوُسٍ عَنْ ابْنِ عَبَّاسٍ أُمِرَ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَسْجُدَ عَلَی سَبْعَةِ أَعْضَائٍ وَلَا يَکُفَّ شَعَرًا وَلَا ثَوْبًا الْجَبْهَةِ وَالْيَدَيْنِ وَالرُّکْبَتَيْنِ وَالرِّجْلَيْنِ
صحیح بخاری · Hadith 809
Narrated Ibn `Abbas: The Prophet was ordered (by Allah) to prostrate on seven parts and not to tuck up the clothes or hair (while praying). Those parts are: the forehead (along with the tip of nose), both hands, both knees, and (toes of) both feet.
