Sunan an-Nasa'i 1087
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ نَصْرِ بْنِ عَاصِمٍ، عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا دَخَلَ فِي الصَّلاَةِ فَذَكَرَ نَحْوَهُ وَزَادَ فِيهِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ فَعَلَ مِثْلَ ذَلِكَ .
Muhammad ibn al-Muthanna reported to us: Mu‘adh ibn Hisham narrated to us; he said: My father narrated to me, from Qatadah, from Nasr ibn ‘Asim, from Malik ibn al-Huwairith, that the Prophet of Allah (ﷺ), when he began the prayer—then he mentioned a similar report, adding: ‘When he bowed, he did likewise; when he raised his head from bowing, he did likewise; and when he raised his head from prostration, he did likewise.’
Translation notes
The Arabic explicitly says the Prophet did likewise when beginning the prayer; فَذَكَرَ نَحْوَهُ refers back to a similar report, then وَزَادَ فِيهِ introduces the additions quoted here.
