[Machine] The Prophet ﷺ would seek refuge from the night two or three times, and when he would stand to pray during the night, he would pray four units of prayer. He would not speak or command anything, and he would send salutations between every two units.
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَسْتَاكُ مِنَ اللَّيْلِ مَرَّتَيْنِ أَوْ ثَلَاثًا وَإِذَا قَامَ يُصَلِّي مِنَ اللَّيْلِ صَلَّى أَرْبَعَ رَكَعَاتٍ لَا يَتَكَلَّمُوَلَا يَأْمُرُ بِشَيْءٍ وَيُسَلِّمُ بَيْنَ كُلِّ رَكْعَتَيْنِ
