Questions on the Explanation of the Book of Nullifiers of Islam

Question:
He says: If one hates a permissible matter or a matter in which there is disagreement, does that fall under the fifth nullifier?

Answer:
A permissible matter or a matter in which there is disagreement has an excuse for the disagreement if the issue is one of scholarly disagreement and he has adopted one of the possibilities or one of the schools of jurisprudence. If he is a mujtahid (a scholar qualified to derive rulings) and is seeking the truth, he is excused. But if he adopted it because it aligns with his desires, there is no doubt that this is an error and he commits a sin for it, but it does not reach the level of apostasy.
