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 " .
Ibn Abbas reported: 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.
