She was afflicted with intrusive thoughts in everything, so how can she get rid of them?

Question:
May Allah reward you with good, and may He do you good. She says about herself: I have been afflicted with intrusive thoughts for a while, as I have come to doubt matters that are certain, such as matters of the unseen. I do not know why I was afflicted with this intrusive thought. I am diligent in keeping the prayers, and for this reason I feel sadness and distress, and I feel that Allah will not accept my good deeds from me. Because of that, I left off many voluntary acts, such as the night prayer and the Duha prayer. Sometimes I pray even the regular voluntary prayers (rawatib), and sometimes I do not pray even the regular voluntary prayers, even though I was previously very diligent in keeping them. Does this mean that Allah is not pleased with me and has not accepted my previous deeds? I ask you to answer this question with a sufficient and satisfying answer. May Allah preserve you. The intrusive thought is from Shaytan.

Answer:
The person should seek refuge in Allah from Shaytan, and he must not pay attention to this intrusive thought, nor take it seriously, but rather reject it completely. He must also not talk about it if his soul whispers to him about it, but rather reject speaking about it. If he acts in accordance with these matters, it will not harm him; this intrusive thought will not harm him, and it will go away from him by the permission of Allah. You should persist in the remembrance of Allah, in good deeds, and in standing in night prayer, and this will go away from you by the permission of Allah. As long as you do not speak about these doubts, which you say may be in matters of creed, as long as you do not speak about this, they will not harm you.
