The Excellence of using Miswak (Tooth-Stick)
وَعَنْ حُذَيْفَةَ رَضِيَ اللَّه عَنْهُ، قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ، إِذَا قام من النوم يشوص فاه بالسواك. ((مُتَّفَقٌ عَلَيْهِ))
Hudaifah (May Allah be pleased with him) reported: Whenever the Messenger of Allah (ﷺ) got up (from sleep), he would rub his teeth with Miswak (tooth-stick). [Al-Bukhari and Muslim].
