Sahih Muslim 2203 a
Uthman b. Abu al-'As reported that he came to Allah's Messenger (ﷺ) and said:
Allah's Messenger, the Satan intervenes between me and my prayer and my reciting of the Qur'an and he confounds me. Thereupon Allah's Messenger (ﷺ) said:, That is (the doing of a) Satan (devil) who is known as Khinzab, and when you perceive its effect, seek refuge with Allah from it and spit three times to your left. I did that and Allah dispelled that from me.
حَدَّثَنَا يَحْيَى بْنُ خَلَفٍ الْبَاهِلِيُّ، حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ سَعِيدٍ الْجُرَيْرِيِّ، عَنْ أَبِي،
 الْعَلاَءِ أَنَّ عُثْمَانَ بْنَ أَبِي الْعَاصِ، أَتَى النَّبِيَّ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ
 الشَّيْطَانَ قَدْ حَالَ بَيْنِي وَبَيْنَ صَلاَتِي وَقِرَاءَتِي يَلْبِسُهَا عَلَىَّ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله
 عليه وسلم ‏
"‏ ذَاكَ شَيْطَانٌ يُقَالُ لَهُ خِنْزِبٌ فَإِذَا أَحْسَسْتَهُ فَتَعَوَّذْ بِاللَّهِ مِنْهُ وَاتْفِلْ عَلَى يَسَارِكَ
 ثَلاَثًا ‏"‏ ‏.‏ قَالَ فَفَعَلْتُ ذَلِكَ فَأَذْهَبَهُ اللَّهُ عَنِّي ‏.‏
