[Machine] Narrated from Witr, the Messenger of Allah ﷺ said, "We used to prepare his purification and toothbrush for him, then Allah would send him to what He wanted to send him in the night. So, he would cleanse himself and perform ablution and then pray nine rak'ahs, in which he would not sit except during the eighth one, where he would praise his Lord and supplicate to Him and remember Him. Then he would rise without giving salaam and perform the ninth rak'ah, in which he would sit and praise his Lord, supplicate, and remember Him. Then he would give salaam audibly for us to hear. After that, he would perform two rak'ahs while sitting, after giving salaam in a state of sitting. Those are the eleven rak'ahs, O my son."
عَنْ وِتْرِ رَسُولِ اللهِ ﷺ قَالَتْ كُنَا نُعِدُّ لَهُ طَهُورَهُ وَسِوَاكَهُ فَيَبْعَثُهُ اللهُ لِمَا شَاءَ أَنْ يَبْعَثَهُ مِنَ اللَّيْلِ «فَيَتَسَوَّكُ وَيَتَوَضَّأُ ثُمَّ يُصَلِّي تِسْعَ رَكَعَاتٍ لَا يَجْلِسُ فِيهِنَّ إِلَّا عِنْدَ الثَّامِنَةِ فَيَحْمَدُ رَبَّهُ وَيَدْعُو وَيَذْكُرُهُ ثُمَّ يَنْهَضُ وَلَا يُسَلِّمُ وَيُصَلِّي التَّاسِعَةَ فَيَجْلِسُ فَيَذْكُرُ رَبَّهُ وَيَحْمَدُهُ وَيَدْعُو ثُمَّ يُسَلِّمُ تَسْلِيمًا يُسْمِعُنَا ثُمَّ يُصَلِّي رَكْعَتَيْنِ وَهُوَ قَاعِدٌ بَعْدَمَا يُسَلِّمُ فَتِلْكَ إِحْدَى عَشْرَةَ رَكْعَةً يَا بُنَيَّ»
