Ibn Abbas reported:
حَدَّثَنَا أَبُو الطَّاهِرِ ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ ، حَدَّثَنِي ابْنُ جُرَيْجٍ ، عَنْ عَبْدِ اللَّهِ بْنِ طَاوُسٍ ، عَنْ أَبِيهِ ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " أُمِرْتُ أَنْ أَسْجُدَ عَلَى سَبْعٍ وَلاَ أَكْفِتَ الشَّعْرَ وَلاَ الثِّيَابَ الْجَبْهَةِ وَالأَنْفِ وَالْيَدَيْنِ وَالرُّكْبَتَيْنِ وَالْقَدَمَيْنِ " .
The Messenger of Allah (ﷺ) said: I was commanded to prostrate myself on the seven (bones) and forbidden to fold back hair and clothing. (The seven bones are): forehead, nose, hands, knees and feet.
