The Prophet (ﷺ) would say this dua. It stops the mind from wanting to do sins.
اَللَّهُمَّ اِنِّي اَعُوذُ بِكَ مِنْ مُنْكَرَاتِ الْاَخْلَاقِ وَالْأَعْمَالِ وَالْأَهْوَاءِ
Transliteration
Allaahumma inni a`udhu bika min munkaraatil-akhlaaqi wal-a`maali wal-ahwaa
Translation
Ziyad bin `Ilaqah narrated from his uncle, that he said: “[The Prophet (ﷺ)] used to say: ‘O Allah, I seek refuge in You from evil character, evil actions, and evil desires (Allāhumma innī a`ūdhu bika min munkarātil-akhlāqi wal-a`māli wal-ahwā’).’”
حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا أَحْمَدُ بْنُ بَشِيرٍ، وَأَبُو أُسَامَةَ عَنْ مِسْعَرٍ، عَنْ زِيَادِ بْنِ عِلاَقَةَ، عَنْ عَمِّهِ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَقُولُ " اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ مُنْكَرَاتِ الأَخْلاَقِ وَالأَعْمَالِ وَالأَهْوَاءِ " . قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ . وَعَمُّ زِيَادِ بْنِ عِلاَقَةَ هُوَ قُطْبَةُ بْنُ مَالِكٍ صَاحِبُ النَّبِيِّ صلى الله عليه وسلم .
