‘A'isha said that the Prophet (ﷺ) did not awake after sleeping by night or by day without using the tooth-stick before performing ablution. Ahmad and Abu Dawud transmitted it.

وَعَنْ عَائِشَةَ قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا يَرْقُدُ مِنْ لَيْلٍ وَلَا نَهَارٍ فَيَسْتَيْقِظُ إِلَّا يَتَسَوَّكُ قَبْلَ أَنْ يَتَوَضَّأَ. رَوَاهُ أَحْمد وَأَبُو دَاوُد
