Narrated Abu Hurairah: (the Prophet, ﷺ ) as saying: Were it not that I might oeverburdern the believers, I would order them to delay the night ('isha ) prayer and use the tooth-stick at the time of every prayer.

Narrated Zayd ibn Khalid al-Juhani: I heard the Messenger of Allah ﷺ say: Were it not hard on my ummah, I would order them to use the tooth-stick at the time of every prayer. Abu Salamah said: Zayd ibn Khalid used to attend the prayers in the mosque with his tooth-stick on his ear where a clerk carries a pen, and whenever he got up for prayer he used it.
