Sunan an-Nasa'i 1103
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا يَزِيدُ، - وَهُوَ ابْنُ هَارُونَ - قَالَ حَدَّثَنَا أَبُو الْعَلاَءِ، - وَاسْمُهُ أَيُّوبُ بْنُ أَبِي مِسْكِينٍ - عَنْ قَتَادَةَ، عَنْ أَنَسٍ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَفْتَرِشْ أَحَدُكُمْ ذِرَاعَيْهِ فِي السُّجُودِ افْتِرَاشَ الْكَلْبِ " .
Ishaq ibn Ibrahim reported to us; he said: Yazid—namely, Ibn Harun—narrated to us; he said: Abu al-‘Ala’—whose name was Ayyub ibn Abi Miskin—narrated to us, from Qatadah, from Anas, from the Messenger of Allah (ﷺ), who said: ‘None of you should spread his forearms on the ground in prostration as a dog spreads them.’
Translation notes
The verb يَفْتَرِشْ conveys spreading or laying out the forearms on the ground; the comparison is to a dog’s posture.
