Narrated Abd Allah b. Shaqiq:

I asked A'ishah about the voluntary prayers offered by the Messenger of Allah (ﷺ). She replied: Before the noon prayer he would pray four rak'ahs in my house, then go out and lead the people in prayer, then return to my house and pray two rak'ahs. He would lead the people in the sunset prayer, then return to my house and pray two rak'ahs. Then he would lead the people in the night prayer, and enter my house and pray two rak'ahs. He would pray nine rak'ahs during the night, including witr (prayer). At night he would pray for a long time standing and for a long time sitting. When he recited the Qur'an while standing, he would bow and prostrate himself from the standing position, and when he recited while sitting, he would bow and prostrate himself from the sitting position, and when dawn came he prayed two rak'ahs, then he would come out and lead the people in the dawn prayer.

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا خَالِدٌ، ح وَحَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا خَالِدٌ، - الْمَعْنَى - عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، قَالَ سَأَلْتُ عَائِشَةَ عَنْ صَلاَةِ، رَسُولِ اللَّهِ صلى الله عليه وسلم مِنَ التَّطَوُّعِ فَقَالَتْ كَانَ يُصَلِّي قَبْلَ الظُّهْرِ أَرْبَعًا فِي بَيْتِي ثُمَّ يَخْرُجُ فَيُصَلِّي بِالنَّاسِ ثُمَّ يَرْجِعُ إِلَى بَيْتِي فَيُصَلِّي رَكْعَتَيْنِ وَكَانَ يُصَلِّي بِالنَّاسِ الْمَغْرِبَ ثُمَّ يَرْجِعُ إِلَى بَيْتِي فَيُصَلِّي رَكْعَتَيْنِ وَكَانَ يُصَلِّي بِهِمُ الْعِشَاءَ ثُمَّ يَدْخُلُ بَيْتِي فَيُصَلِّي رَكْعَتَيْنِ وَكَانَ يُصَلِّي مِنَ اللَّيْلِ تِسْعَ رَكَعَاتٍ فِيهِنَّ الْوِتْرُ وَكَانَ يُصَلِّي لَيْلاً طَوِيلاً قَائِمًا وَلَيْلاً طَوِيلاً جَالِسًا فَإِذَا قَرَأَ وَهُوَ قَائِمٌ رَكَعَ وَسَجَدَ وَهُوَ قَائِمٌ وَإِذَا قَرَأَ وَهُوَ قَاعِدٌ رَكَعَ وَسَجَدَ وَهُوَ قَاعِدٌ وَكَانَ إِذَا طَلَعَ الْفَجْرُ صَلَّى رَكْعَتَيْنِ ثُمَّ يَخْرُجُ فَيُصَلِّي بِالنَّاسِ صَلاَةَ الْفَجْرِ صلى الله عليه وسلم ‏.‏
