Sunan an-Nasa'i 1094
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا بَكْرٌ، 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 مِنْهُ سَبْعَةُ آرَابٍ وَجْهُهُ وَكَفَّاهُ وَرُكْبَتَاهُ وَقَدَمَاهُ " .
Qutaybah reported to us; he said: Bakr narrated to us, from Ibn al-Had, from Muhammad ibn Ibrahim, from ‘Amir ibn Sa‘d, from al-‘Abbas ibn ‘Abd al-Muttalib, who heard the Messenger of Allah (ﷺ) say: ‘When a servant prostrates, seven parts of him prostrate: his face, his two palms, his two knees, and his two feet.’
Translation notes
The Arabic word آرَابٍ refers here to body parts; the narration itself lists the face, palms, knees, and feet, totaling seven.
