وَعَنْ عَائِشَةَ
قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: لَا يَرْقُدُ مِنْ لَيْلٍ وَلَا نَهَارٍ فَيَسْتَيْقِظُ إِلَّا يَتَسَوَّكُ قَبْلَ أَنْ يَتَوَضَّأَ
Aishah said that the Prophet (sallallahu alayhi wa sallam) did not awake after sleeping by night or by day without using the tooth-stick before performing ablution.
