[Machine] The Messenger of Allah ﷺ used to sleep, and when he woke up, he would rose up and perform ablution, then pray eight units of prayer. He would sit after every two units, and then conclude by sitting in the fifth unit. After that, he would perform Witr prayer consisting of five units, sitting only in the fifth unit, and then conclude the prayer.
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَرْقُدُ فَإِذَا اسْتَيْقَظَ تَسَوَّكَ ثُمَّ تَوَضَّأَ ثُمَّ صَلَّى ثَمَانِ رَكَعَاتٍ يَجْلِسُ فِي كُلِّ رَكْعَتَيْنِ فَيُسَلِّمُ ثُمَّ يُوتِرُ بِخَمْسِ رَكَعَاتٍ لَا يَجْلِسُ إِلَّا فِي الْخَامِسَةِ وَلَا يُسَلِّمُ إِلَّا فِي الْخَامِسَةِ
