“"Uthman bin Abul-As (radi allāhu’ anhū) came and said to the Prophet ﷺ “O Messenger of Allah, Shaytan is spoiling my prayers and confusing my reciting of the Qur’an.

The Messenger of Allah ﷺ said: “That is a shaytan called Khinzab, so if you feel that (he is around) say: ‘I seek refuge with Allah from you.” Then blow breath with light spit on your left three times.”

Uthman said: “I did that and Allah took him away from me.””
