Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ حَدَّثَنَا وَاصِلٌ عَنْ أَبِي سَوْرَةَ عَنْ أَبِي أَيُّوبَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَسْتَاكُ مِنْ اللَّيْلِ مَرَّتَيْنِ أَوْ ثَلَاثًا وَإِذَا قَامَ يُصَلِّي مِنْ اللَّيْلِ صَلَّى أَرْبَعَ رَكَعَاتٍ لَا يَتَكَلَّمُ وَلَا يَأْمُرُ بِشَيْءٍ وَيُسَلِّمُ بَيْنَ كُلِّ رَكْعَتَيْنِ وَبِهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا تَوَضَّأَ تَمَضْمَضَ وَمَسَحَ لِحْيَتَهُ مِنْ تَحْتِهَا بِالْمَاءِ.
English Translation
Muhammad ibn Ubayd narrated to us, Wasil narrated to us, from Abu Sawrah, from Abu Ayyub: that the Messenger of Allah, peace and blessings be upon him, used to use the tooth-stick at night twice or three times, and when he rose to pray at night, he would pray four rak'ahs, not speaking nor commanding anything, giving the taslim after every two rak'ahs. And by the same chain: that the Messenger of Allah, peace and blessings be upon him, whenever he performed ablution, would rinse his mouth and wipe his beard from underneath with water.
