Sunan an-Nasa'i 1090
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نَافِعٍ، عَنْ مُحَمَّدِ بْنِ عَبْدِ اللَّهِ بْنِ حَسَنٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " يَعْمِدُ أَحَدُكُمْ فِي صَلاَتِهِ فَيَبْرُكَ كَمَا يَبْرُكُ الْجَمَلُ " .
Qutaybah reported to us; he said: ‘Abdullah ibn Nafi‘ narrated to us, from Muhammad ibn ‘Abdullah ibn Hasan, from Abu al-Zinad, from al-A‘raj, from Abu Hurairah, who said: The Messenger of Allah (ﷺ) said: ‘Does one of you, while praying, deliberately kneel down as a camel kneels?’
Translation notes
The Arabic uses يَعْمِدُ (deliberately/sets out to) and فَيَبْرُكُ (kneels or sinks down); the English witness recasts the statement as a question, which is retained here.
