It was narrated that Ibn 'Abbas said: "The Messenger of Allah used to pray in the night (Qiyamul-Lail) two Rak'ah by two, then when he finished he would use the tooth stick".
The hadith teaches us about the importance of taking care of our physical health while also engaging in spiritual practices such as prayer or reciting Quran verses with purity of heart and mind. It also shows us how devoted the Prophet Muhammad was to his faith and how we should strive to emulate him in our own lives by following his example whenever possible.
