Safety From Evil (Dua)

Ibn Taymiyyah said:

“And Satan is a whisperer who withdraws, if the servant makes remembrance of his Lord; he withdraws, and if he becomes negligent in remembrance of Him; he whispers. It is due to this that the abandonment of the remembrance of Allah is a reason as well as a basis for the descent of false belief and corrupt intent into the heart.”

Majmu’ Fatawa vol 4 p.34

And he also said:

“Silence void of recitation or dhikr (remembrance of Allaah) or du’a (supplication) is not worship, nor has it been commanded with. Rather it opens the door to whispering, therefore preoccupation with the remembrance of Allah is better than being silent.”

Majmu’ Fatawa vol 23 p.285-286

So if you are suffering with waswas then recite more Quran and make lots of dua such as the one above as Ibn Qayyim said:

“The Qur’an is a cure for that which is in the chests, a repeller of that which Satan casts into it by way of whisperings and desires and corrupt intents.”
