Chapter 45: Prostrating on the knees - كتاب التطبيق
أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ الْمَكِّيُّ، وَعَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ الزُّهْرِيُّ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، أُمِرَ النَّبِيُّ صلى الله عليه وسلم أَنْ يَسْجُدَ عَلَى سَبْعٍ - وَنُهِيَ أَنْ يَكْفِتَ الشَّعْرَ وَالثِّيَابَ - عَلَى يَدَيْهِ وَرُكْبَتَيْهِ وَأَطْرَافِ أَصَابِعِهِ . قَالَ سُفْيَانُ قَالَ لَنَا ابْنُ طَاوُسٍ وَوَضَعَ يَدَيْهِ عَلَى جَبْهَتِهِ وَأَمَرَّهَا عَلَى أَنْفِهِ . قَالَ هَذَا وَاحِدٌ وَاللَّفْظُ لِمُحَمَّدٍ .
It was narrated from Ibn 'Abbas:
"The Prophet (ﷺ) was commanded to prostrate on seven-and he was forbidden to tuck up his hair and garment-on his hands, his knees, the edges of his feet." Sufyan said: "Ibn Tawus said to us: 'He put his hand on his forehead and moved it down to his nose and said: This one thing.'"
