A person with excessive intrusive thoughts regarding intention in prayer

Question:
May Allah reward you with good. She asks the Honorable Shaykh, among her questions, that when she says, "I intend to pray an obligatory prayer," intrusive thoughts come to her regarding her intention. When she wants to pray the 'Asr prayer, intrusive thoughts come to her, telling her that it is not 'Asr but rather Zuhr or a voluntary prayer, while her intention is that it is the obligatory 'Asr prayer. Is her prayer valid? Does the intention change because of these intrusive thoughts? And what should she do?

Answer:
First, the intention is the purpose and resolve in the heart, and it is not permissible to vocalize it, because vocalizing it is a religious innovation (bid'ah), since the Prophet (peace and blessings be upon him) did not do it, nor did his Companions, nor did anyone from the Salaf. Vocalizing the intention is a religious innovation (bid'ah); rather, the intention in the heart is sufficient. The heart resolves it. As for the intrusive thoughts that afflict a person—whether he intended or did not intend, or what the intention is, or this or that—people reject these and do not pay attention to them. When a person stands to pray or comes to the prayer, he has intended. If he comes to the prayer or stands for the prayer, he has intended. So there is no need for the intrusive thoughts, and one should not pay attention to them. Rather, he intends the prayer, says the takbir, and completes his prayer, and does not pay attention to Satan telling him, "You did not intend what you intended," or "You broke your intention," or similar matters that confuse the servant in his worship, and Satan takes advantage of him in them. Yes.
