حَدَّثَنَا بَهْزٌ حَدَّثَنَا شُعْبَةُ حَدَّثَنَا عَمْرُو بْنُ دِينَارٍ قَالَ سَمِعْتُ طَاوُسًا يُحَدِّثُ عَنِ ابْنِ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ أُمِرْتُ أَنْ أَسْجُدَ عَلَى سَبْعَةِ أَعْظُمٍ وَلَا أَكُفَّ شَعَرًا وَلَا ثَوْبًا وَقَالَ مَرَّةً أُخْرَى أُمِرَ نَبِيُّكُمْ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَسْجُدَ عَلَى سَبْعَةِ أَعْظُمٍ وَلَا يَكُفَّ شَعَرًا وَلَا ثَوْبًا
مسند امام احمد بن حنبل · Hadith 2527
It was narrated from Ibn 'Abbas (RA) that the Messenger of Allah (PBUH) said: "I was commanded to prostrate on seven bones and not to tuck up my hair or garment." And on another occasion he said: Your Prophet (PBUH) was commanded to prostrate on seven bones, and not to tuck up his hair or garment.
