Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن عائشة رضي الله عنها، قالت: كنا نعد لرسول الله، سواكه وطهوره، فيبعثه الله ما شاء أن يبعثه من الليل، فيتسوك ويتوضأ ويصلي. ((رواه مسلم)).
We used to prepare for the Messenger of Allah (ﷺ) a Miswak (tooth-stick) and the water for making Wudu'. Whenever Allah wished to awaken him from sleep at night, he (ﷺ) would brush his teeth with Miswak, make Wudu', and perform Salat.[Muslim].
