Messenger of Allah, the Satan intervenes between me and my prayer and my reciting of the Qur'an and he confounds me. Thereupon Messenger of Allah 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.  

أَنَّ عُثْمَانَ بْنَ أَبِي الْعَاصِ أَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ الشَّيْطَانَ قَدْ حَالَ بَيْنِي وَبَيْنَ صَلاَتِي وَقِرَاءَتِي يَلْبِسُهَا عَلَىَّ فَقَالَ رَسُولُ اللَّهِ ﷺ ذَاكَ شَيْطَانٌ يُقَالُ لَهُ خِنْزِبٌ فَإِذَا أَحْسَسْتَهُ فَتَعَوَّذْ بِاللَّهِ مِنْهُ وَاتْفِلْ عَلَى يَسَارِكَ ثَلاَثًا قَالَ فَفَعَلْتُ ذَلِكَ فَأَذْهَبَهُ اللَّهُ عَنِّي  

'Uthman b. Abu al-'As reported that he came to Allah's Apostle ﷺ and he narrated like this. In the hadith transmitted on the authority of Salam b. Nuh there is no mention of three times,  

أَنَّهُ أَتَى النَّبِيَّ ﷺ فَذَكَرَ بِمِثْلِهِ وَلَمْ يَذْكُرْ فِي حَدِيثِ سَالِمِ بْنِ نُوحٍ ثَلاَثًا  

This hadith has been transmitted on the authority of 'Uthman b. Abu al-'As with a slight variation of wording.  

قُلْتُ يَا رَسُولَ اللَّهِ ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِهِمْ
