‘Uthman b. Abul-'As said he told God’s messenger that the devil interfered with his prayer and his recitation of the Qur’an, causing confusion in his mind, and God’s messenger replied, “That is a devil called Khinzab; so when you feel his presence seek refuge from him in God and spit three times on your left side.” ‘Uthman did so and God caused him to depart from him. Muslim transmitted it.

Hadith Takhrij´تحقيق و تخريج: محدث العصر حافظ زبير على زئي رحمه الله` «رواه مسلم (68/ 2203)»
Fiqh al-Hadith: ➊ The name of the devil who is set upon those performing prayer is Khanzab. In a fabricated (mawdu‘) narration from Ghunyat al-Talibin, the word “hadith” appears, which is a scribal error. ➋ One should act upon the methods for protection from satanic whisperings (waswasah) that are mentioned in authentic ahadith, so that Allah, by His grace and mercy, may safeguard one from these whisperings.
