Does changing one's opinion and acting in a way that contradicts previous advice given to others fall under the category of "saying what they do not do," as mentioned in the description of the hypocrites?

If you prohibited something thinking it was wrong, then it became clear to you that it was correct, and you retracted your prohibition and did it, this is not hypocrisy; rather, it is one of the characteristics of believers. However, if you prohibited something that you considered wrong, and then you did it while still believing it to be wrong, this is blameworthy, as indicated by Allah's saying: "Do you order people to righteousness and forget yourselves?" and "Great is hatred in the sight of Allah that you say what you do not do." But this does not justify abandoning enjoining what is right and forbidding what is wrong, for it is not a condition that the one who prohibits be without any shortcomings. However, if the prohibition is of what is right, then this is one of the characteristics of the hypocrites, as stated in Allah's saying: "The hypocrite men and hypocrite women are of one another. They enjoin what is wrong and forbid what is right."
