Is raising one's voice at one's parents or objecting to their words considered a form of disobedience (ʿuqūq)? Does this invalidate one's deeds? And is the sadness and abandonment of worship that the questioner is experiencing due to these thoughts considered to be from the whispers of Satan?

A son must be dutiful and kind to his parents. If he discusses matters with them, it should be with goodness, humility, and a lowered voice. Mere literary disagreement with them is not considered disobedience (ʿuquq) if the son is in the right, but it is better to avoid discussing non-religious matters with them. Raising one's voice at them is forbidden, and disobedience is not an act that invalidates good deeds. The son must repent for angering his parents and for any shortcomings in worship. He must also distance himself from the whispers of Satan, seek righteous companionship, frequently recite the Quran, attend scholarly gatherings, and be diligent in performing congregational prayers.
