Arabic (Original)
حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ مَنْصُورٍ عَنْ أَبِي وَائِلٍ عَنْ حُذَيْفَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا قَامَ مِنْ اللَّيْلِ يَشُوصُ فَاهُ بِالسِّوَاكِ.

Sufyan b. 'Uyaynah told us, from Mansur, from Abu Wa'il, from Hudhayfah: that the Prophet (peace and blessings be upon him), when he rose at night, would rub his mouth vigorously with the tooth-stick.
