It was narrated that Hudhaifah said:
"When the Messenger of Allah ﷺ got up to pray tahajjud at night, he would brush his teeth with the siwak.
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ حُصَيْنٍ، قَالَ سَمِعْتُ أَبَا وَائِلٍ، يُحَدِّثُ عَنْ حُذَيْفَةَ، قَالَ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَامَ مِنَ اللَّيْلِ يَشُوصُ فَاهُ بِالسِّوَاكِ .
