356. Dua against Shaytan Whisper
If you notice the presence of Satan in the prayer, say this dua and spit three times on the left side -
أَعُوْذُ بِاللَّهِ مِنَ الشَّيْطَانِ الرَّجِيمِ
اَعُوْذُ بِاللّٰهِ مِنْ الشَّيْطَانِ الرَّجِيْمِ
A‛oodhu billaahi minash-Shaytaanir-rajeem
Translation
I seek refuge in Allah from Satan the outcast.
