Does doubting the Earth's stability and the Sun's revolution around it—contrary to what is established in the Qur'an and Sunnah and what some scholars have stated—lead to apostasy, given that this doubt arose from whispers and questions, along with a repulsion from anything that contradicts the Qur'an and Sunnah?

The issue of whether the Earth rotates or not is a scientific and natural matter. The Sharia did not explicitly intend to clarify it, as it is not among the matters for which the Quran was revealed. Proving or denying it does not affect faith. Rather, the apparent meanings of religious texts can be interpreted in a way that aligns with proven scientific facts.
