What is the remedy for one who is afflicted with frequent intrusive thoughts (waswas) in prayer and other acts of worship, and is she sinful for having them?

Question:
May Allah bless you. This is a message from your sister in Allah, J.J. In her first question, she says that she is a veiled woman and praises Allah for that, and she performs some righteous deeds as much as she can. But she always says, “I feel intrusive thoughts in my prayer and all my deeds, and in every place. And every time I try to distance myself from these intrusive thoughts, they return to me. So, am I sinful for that? I hope you will guide me with something that will keep these intrusive thoughts away from me?”

Answer:
A person is not held accountable for intrusive thoughts because they occur without his choice. However, he must do the things that repel these intrusive thoughts from him. These include increasing the remembrance of Allah, seeking refuge in Allah from the accursed Shaytan, and increasing that. He should also not pay attention to the intrusive thoughts, not be affected by them, and reject them completely without caring about them. By the permission of Allah, these are the means for their removal. As for sin, a person does not sin because of these intrusive thoughts because they occur without his choice. Yes.
