Never did I see the Messenger of Allah ﷺ observing supererogatory prayer sitting till one year before his death when he would observe Nafl prayer in a sitting position, and he would recite the Surah (of the Qur'an) in such a slow-measured tone (that duration of its recital) became more lengthy than the one longer than this.  

أَنَّهَا قَالَتْ مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى فِي سُبْحَتِهِ قَاعِدًا حَتَّى كَانَ قَبْلَ وَفَاتِهِ بِعَامٍ فَكَانَ يُصَلِّي فِي سُبْحَتِهِ قَاعِدًا وَكَانَ يَقْرَأُ بِالسُّورَةِ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا  

"I never saw the Messenger of Allah ﷺ offer his voluntary prayers sitting down until one year before his death. Then he used to pray sitting down, reciting the surah so slowly that it seemed to be longer than a surah that is longer."  

مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى فِي سُبْحَتِهِ قَاعِدًا قَطُّ حَتَّى كَانَ قَبْلَ وَفَاتِهِ بِعَامٍ فَكَانَ يُصَلِّي قَاعِدًا يَقْرَأُ بِالسُّورَةِ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا  

"I did not see Messenger of Allah (S) praying voluntary prayers sitting until the year before he died. Then he would perform Salat for the voluntary prayers sitting, and he would recite a Surah and prolong it such that it would be longer than the longest of them."  

عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى فِي سُبْحَتِهِ قَاعِدًا حَتَّى كَانَ قَبْلَ وَفَاتِهِ ﷺ بِعَامٍ فَإِنَّهُ كَانَ يُصَلِّي فِي سُبْحَتِهِ قَاعِدًا وَيَقْرَأُ بِالسُّورَةِ وَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا وَفِي الْبَابِ عَنْ أُمِّ سَلَمَةَ وَأَنَسِ بْنِ مَالِكٍ  

Yahya related to me from Malik from Ibn Shihab from as-Sa'ib ibn Yazid from al Muttalib ibn Abi Wadaa as-Sahmi that Hafsa, the wife of the Prophet ﷺ said, "I never saw the Messenger of Allah ﷺ praying nawafil sitting, until a year before his death, when he began to pray them sitting. He would recite the sura with a measured slowness so that it would seem to be longer than other suras which were actually longer than it."  

عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى فِي سُبْحَتِهِ قَاعِدًا قَطُّ حَتَّى كَانَ قَبْلَ وَفَاتِهِ بِعَامٍ فَكَانَ يُصَلِّي فِي سُبْحَتِهِ قَاعِدًا وَيَقْرَأُ بِالسُّورَةِ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا  

that she said, "I never saw the Messenger of Allāh ﷺ pray his supererogatory prayers while sitting; until a year before his passing when he would his supererogatory prayers while sitting and reciting the sūrah in ˹such a slow˺ measured manner that it became longer than his ˹usual˺ longer ones."  

أَنَّهَا قَالَتْ لَمْ أَرَ رَسُولَ اللهِ ﷺ يُصَلِّي فِي سُبْحَتِهِ جَالِسًا قَطُّ حَتَّى إِذَا كَانَ قَبْلَ مَوْتِهِ بِعَامٍ أَوْ بِعَامَيْنِ فَكَانَ يُصَلِّي فِي سُبْحَتِهِ جَالِسًا وَيَقْرَأُ السُّورَةَ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا  

that she said, "I never saw the Messenger of Allāh ﷺ pray his supererogatory prayers while sitting; until a year before his passing when he would his supererogatory prayers while sitting and reciting the sūrah in ˹such a slow˺ measured manner that it became longer than his ˹usual˺ longer ones." (Using translation from Aḥmad 26441)   

مَا رَأَيْتُ رَسُولَ اللهِ ﷺ يُصَلِّي فِي سُبْحَتِهِ جَالِسًا قَطُّ حَتَّى كَانَ قَبْلَ مَوْتِهِ بِعَامٍ فَكَانَ يُصَلِّي جَالِسًا فَيَقْرَأُ السُّورَةَ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا  

that she said, "I never saw the Messenger of Allāh ﷺ pray his supererogatory prayers while sitting; until a year before his passing when he would his supererogatory prayers while sitting and reciting the sūrah in ˹such a slow˺ measured manner that it became longer than his ˹usual˺ longer ones." (Using translation from Aḥmad 26441)   

«مَا رَأَيْتُ النَّبِيَّ ﷺ صَلَّى فِي سُبْحَتِهِ جَالِسًا قَطُّ حَتَّى كَانَ قَبْلَ وَفَاتِهِ بِعَامٍ فَكَانَ يُصَلِّي فِي سُبْحَتِهِ جَالِسًا فَيَقْرَأُ السُّورَةَ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا»  

[Machine] Narrated by Hafsah, the wife of the Prophet Muhammad ﷺ , she informed him saying, "I never saw the Messenger of Allah ﷺ praying while sitting until a year before his death. He would pray in his tasbeeh (subh) while sitting, reciting the Surah slowly, making it longer than it actually was."  

عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا أَخْبَرَتْهُ قَالَتْ «مَا رَأَيْتُ رَسُولَ اللهِ ﷺ يُصَلِّي قَاعِدًا قَطُّ حَتَّى كَانَ قَبْلَ مَوْتِهِ بِعَامٍ فَكَانَ يُصَلِّي فِي سُبْحَتِهِ قَاعِدًا وَيَقْرَأُ بِالسُّورَةِ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا»  

[Machine] "I have never seen the Messenger of Allah ﷺ praying while sitting in his prayer mat until one or two years before his death. I saw him praying while sitting in his prayer mat and reciting the Surah until his recitation of it became longer than the length of the Surah itself."  

«مَا رَأَيْتُ رَسُولَ اللهِ ﷺ قَاعِدًا فِي سُبْحَتِهِ حَتَّى كَانَ قَبْلَ مَوْتِهِ بِعَامٍ وَاحِدٍ أَوِ اثْنَيْنِ فَرَأَيْتُهُ يُصَلِّي قَاعِدًا فِي سُبْحَتِهِ وَيُرَتِّلُ السُّورَةَ حَتَّى يَكُونَ قِرَاءَتُهَا إِيَّاهَا أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا»  

[Machine] "Hafsah, the wife of the Prophet ﷺ, said: 'I never saw the Messenger of Allah ﷺ praying in his Sibha (prayer beads) until he was close to passing away a year or two, so I saw him praying seated with his Sibha, reciting the Surah until his recitation was longer than any other recitation.'"  

عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ ﷺ قَالَتْ «لَمْ أَرَ رَسُولَ اللهِ ﷺ قَاعِدًا فِي سُبْحَتِهِ حَتَّى كَانَ قَبْلَ أَنْ يُتَوَفَّى بِعَامٍ وَاحِدٍ أَوِ اثْنَيْنِ فَرَأَيْتُهُ يُصَلِّي قَاعِدًا فِي سُبْحَتِهِ يُرَتِّلُ السُّورَةَ حَتَّى يَكُونَ فِي قِرَاءَتِهِ أَطْوَلَ مِنْ أَطْوَلَ مِنْهَا»  

"I never saw the Messenger of Allah ﷺ offer his voluntary prayers sitting down until one year before his death. Then he used to pray sitting down, reciting the surah so slowly that it seemed to be longer than a surah that is longer." (Using translation from Nasāʾī 1658)  

مَا رَأَيْتُ رَسُولَ اللهِ ﷺ صَلَّى فِي سُبْحَتَهُ قَاعِدًا قَطُّ حَتَّى كَانَ قَبْلَ وَفَاتِهِ بِعَامٍ فَكَانَ «يُصَلِّي قَاعِدًا وَيُقْرَأُ بِالسُّورَةِ فَيُرَتِّلُهَا حَتَّى تَكُونَ أَطْوَلَ مِنْ أَطْوَلِ مِنْهَا»
