(the mother of the faithful believers) Messenger of Allah ﷺ (in his last days) used to pray sitting. He would recite while sitting, and when thirty or forty verses remained from the recitation he would get up and recite them while standing and then he would bow and prostrate. He used to do the same in the second rakʿa. After finishing the Prayer he used to look at me and if I was awake he would talk to me and if I was asleep, he would lie down.  

عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ ؓ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي جَالِسًا فَيَقْرَأُ وَهْوَ جَالِسٌ فَإِذَا بَقِيَ مِنْ قِرَاءَتِهِ نَحْوٌ مِنْ ثَلاَثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَهَا وَهْوَ قَائِمٌ ثُمَّ يَرْكَعُ ثُمَّ يَسْجُدُ يَفْعَلُ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ فَإِذَا قَضَى صَلاَتَهُ نَظَرَ فَإِنْ كُنْتُ يَقْظَى تَحَدَّثَ مَعِي وَإِنْ كُنْتُ نَائِمَةً اضْطَجَعَ  

The Messenger of Allah ﷺ used to pray while sitting (when he grew old) and he recited in this position and when the recitation equal to thirty or forty verses was left, he would then stand up and recite (for this duration) in a standing position and then bowed himself and then prostrated himself and did the same in the second rak'ah.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي جَالِسًا فَيَقْرَأُ وَهُوَ جَالِسٌ فَإِذَا بَقِيَ مِنْ قِرَاءَتِهِ قَدْرُ مَا يَكُونُ ثَلاَثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَ وَهُوَ قَائِمٌ ثُمَّ رَكَعَ ثُمَّ سَجَدَ ثُمَّ يَفْعَلُ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ  

The Prophet ﷺ used to pray when he was sitting. He would recite while sitting, then when there were thirty or forty verses left, he would stand up and recite while standing, then he bowed and prostrated, then he would do likewise in the second rak'ah.  

أَنَّ النَّبِيَّ ﷺ كَانَ يُصَلِّي وَهُوَ جَالِسٌ فَيَقْرَأُ وَهُوَ جَالِسٌ فَإِذَا بَقِيَ مِنْ قِرَاءَتِهِ قَدْرُ مَا يَكُونُ ثَلاَثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَ وَهُوَ قَائِمٌ ثُمَّ رَكَعَ ثُمَّ سَجَدَ ثُمَّ يَفْعَلُ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ  

"The Prophet (S) would perform Salat while sitting. And he would recite while sitting. When about thirty or forty Ayah of his recitation remained he would standup and recite while he was standing, then he would bow and prostrate. Then he would do the same in the second Rak'ah."  

أَنَّ النَّبِيَّ ﷺ كَانَ يُصَلِّي جَالِسًا فَيَقْرَأُ وَهُوَ جَالِسٌ فَإِذَا بَقِيَ مِنْ قِرَاءَتِهِ قَدْرُ مَا يَكُونُ ثَلاَثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَ وَهُوَ قَائِمٌ ثُمَّ رَكَعَ وَسَجَدَ ثُمَّ صَنَعَ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ  

Yahya related to me from Malik from Abdullah ibn Yazid al-Madani and from Abu'n Nadr from Abu Salama ibn Abd ar-Rahman from A'isha, the wife of the Prophet ﷺ that the Messenger of Allah ﷺ used to pray sitting. He would recite sitting, and then, when about thirty or forty ayats of what he was reciting remained, he would stand up and recite standing and then go into ruku and sajda. He would do the same in the second raka.  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي جَالِسًا فَيَقْرَأُ وَهُوَ جَالِسٌ فَإِذَا بَقِيَ مِنْ قِرَاءَتِهِ قَدْرُ مَا يَكُونُ ثَلاَثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَ وَهُوَ قَائِمٌ ثُمَّ رَكَعَ وَسَجَدَ ثُمَّ صَنَعَ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ  

The Messenger of Allah ﷺ used to pray while sitting (when he grew old) and he recited in this position and when the recitation equal to thirty or forty verses was left, he would then stand up and recite (for this duration) in a standing position and then bowed himself and then prostrated himself and did the same in the second rak'ah. (Using translation from Muslim 731b)  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُصَلِّيجَالِسًا فَيَقْرَأُ وَهُوَ جَالِسٌ فَإِذَا بَقِيَ عَلَيْهِ مِنْ قِرَاءَتِهِ قَدْرُ مَا يَكُونُ ثَلَاثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَ وَهُوَ قَائِمٌ ثُمَّ رَكَعَ ثُمَّ سَجَدَ ثُمَّ يَفْعَلُ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ  

when the prophet ﷺ prayed sitting, he recited the Quran in sitting condition. When the amount of his recitation remained about thirty or forty verses he stood up and recited them standing. He then bowed and prostrated and then did so in the second Rak’ah of the prayer. Abu Dawud said: 'Alqamah b. Waqqas narrated this tradition on the authority of 'Aishah from the Prophet ﷺ to the same effect. (Using translation from Abū Dāʾūd 954)   

رَسُولَ اللهِ ﷺ كَانَ يُصَلِّي جَالِسًا فَيَقْرَأُ وَهُوَ جَالِسٌ فَإِذَا بَقِيَ مِنْ قَرَاءَتِهِ قَدْرُ مَا يَكُونُ ثَلَاثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَ وَهُوَ قَائِمٌ ثُمَّ رَكَعَ ثُمَّ سَجَدَ ثُمَّ يَفْعَلُ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ
