Is the belief in the validity of affirming the attributes of Allah mentioned in the Qur’an and Sunnah, and denying what is other than them, correct? And how can one know the attributes of Allah to get rid of the whispers of Iblees that claim the existence of other attributes for Allah, such as "intention"? And will one who denies an attribute, believing it to be from a whisper, be held accountable? And does asking about this with the intention of clarifying ambiguity lead to sin?

Any attributes of Allah Almighty that are not mentioned in the Quran or Sunnah must be left unaddressed, neither denied nor affirmed. If the unaddressed attribute is a pure perfection and can be ascribed to the Creator, then it falls under His saying, "And to Allah belongs the highest example; and He is the Exalted in Might, the Wise" (Quran 16:60). Every perfection established for the created that can be attributed to the Creator is more befitting for the Creator. The root of the questioner's problem is waswasah (whispers/obsessive thoughts), and she is advised to distance herself from them and not to indulge in them.
