Answered by Shaykh Yusuf Weltch
Question
Will I be accountable if my doubts prove to be true on the Day of Judgment?
Answer
In the Name of Allah, the Most Merciful and Compassionate
On the Day of Judgment, people will be judged according to what they were religiously responsible for. When the scholars advise someone to ignore their doubts, this is because they are not responsible to act upon doubts.
In this thread, you can see why you need not worry about being accountable regarding doubts possibly being true. In essence, you did what was asked of you and what was in your ability. Acting on doubts would necessitate or result in undue hardship.
Allah Most High says, “Strive for ˹the cause of˺ Allah in the way He deserves, for ˹it is˺ He ˹Who˺ has chosen you, and laid upon you no hardship in the religion—the way of your forefather Abraham.” [Quran, 22:78]
Hardship is not part of the religion, and in fact the religion seeks to remove hardships. [Ibn Nujaym; al-Ashbah wa al-Nazair]
Thus, ignoring the doubts is entirely in-line with what Allah Most High wants, even in the case that they turn out to be true (which is highly unlikely).
Hope this helps
Allah knows best
