Uthman bin Abu As reported,

He came to the Prophet ﷺ and said, "Messenger of Allah, Satan has come between me and my prayer and my recitation, confusing them for me."The Messenger of Allah ﷺ replied, "That is a devil called Khinzab. When you sense him, seek refuge in Allah from him and spit lightly to your left three times."He said, "I did that, and Allah drove him away from me."

Sahih

عن عثمان بن أبي العاص

أنه أتى النبي ﷺ فقال: يا رسول الله إن الشيطان قد حال بيني وبين صلاتي وقراءتي يلبسها علي. فقال رسول الله ﷺ: ذاك شيطان يقال له خنزب، فإذا أحسسته فتعوذ بالله منه واتفل على يسارك ثلاثا. قال: ففعلت ذلك فأذهبه الله عني.
