Whoever starts his Salat sitting (because of ailment) and then during the Salat (prayer) feels better, can finish the rest while standing
باب إِذَا صَلَّى قَاعِدًا ثُمَّ صَحَّ أَوْ وَجَدَ خِفَّةً تَمَّمَ مَا بَقِيَ
Sahih al-Bukhari, Book of Shortening the Prayers (At-Taqseer)(view book)
Narrated Aisha:
(the mother of the faithful believers) I never saw Allah's Apostle offering the night prayer while sitting except in his old age and then he used to recite while sitting and whenever he wanted to bow he would get up and recite thirty or forty verses (while standing) and then bow.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أُمِّ الْمُؤْمِنِينَ أَنَّهَا أَخْبَرَتْهُ أَنَّهَا لَمْ تَرَ رَسُولَ اللَّهِ ﷺ يُصَلِّي صَلاَةَ اللَّيْلِ قَاعِدًا قَطُّ حَتَّى أَسَنَّ، فَكَانَ يَقْرَأُ قَاعِدًا حَتَّى إِذَا أَرَادَ أَنْ يَرْكَعَ قَامَ، فَقَرَأَ نَحْوًا مِنْ ثَلاَثِينَ آيَةً أَوْ أَرْبَعِينَ آيَةً، ثُمَّ رَكَعَ.

Narrated 'Aisha:
(the mother of the faithful believers) Allah's Apostle (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 Raka. 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.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، وَأَبِي النَّضْرِ، مَوْلَى عُمَرَ بْنِ عُبَيْدِ اللَّهِ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ ـ رضى الله عنها ـ 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.
