Is saying "Uff" or "Yeeeh" when parents ask their son for something forbidden and included in the prohibition, even if said out of earshot of the parents?

Dealing with parents requires good manners, gentleness, humility, and reverence. The prohibition against scolding them or speaking harshly to them includes everything that expresses annoyance or displeasure towards them, as Allah Almighty says: "So do not say to them, 'uff,' and do not repel them but speak to them a noble word. And lower to them the wing of humility out of mercy and say, 'My Lord, have mercy upon them as they brought me up when I was small.'" The prohibition of "uff" includes the lowest degrees of harm. However, if annoyance and displeasure are not manifested to the parents, they do not fall under this prohibition. Nevertheless, a child should strive to avoid uttering anything that expresses annoyance and should meet their commands with satisfaction and good cheer, bearing in mind a good intention and the great reward for honoring parents.
