حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا بَكْرٌ، - وَهُوَ ابْنُ مُضَرَ - عَنِ ابْنِ الْهَادِ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ عَامِرِ بْنِ سَعْدٍ، عَنِ الْعَبَّاسِ بْنِ عَبْدِ الْمُطَّلِبِ، أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِذَا سَجَدَ الْعَبْدُ سَجَدَ مَعَهُ سَبْعَةُ أَطْرَافٍ وَجْهُهُ وَكَفَّاهُ وَرُكْبَتَاهُ وَقَدَمَاهُ " .
It was narrated from Al-'Abbas bin 'Abdul Muttalib that he heard the Messenger of Allah (ﷺ) say:
"When a person prostates, he prostates on seven part of the body: His face, his hands, his knees and his feet."
