What is the religious ruling on swearing a false oath on the Qur’an in a state of anger to change an electronic account password, while feeling guilty and attempting to expiate by giving charity, fasting, and seeking forgiveness from the account holder?

The "yamin (definition) ghamus" (a false oath taken deliberately) regarding a past event, contrary to what actually happened, is considered one of the major sins. Similarly, transgressing against someone else's account by changing the password is a religiously forbidden sin. These actions are not excused by the swearer's anger or impulsiveness, as long as their sanity remains intact. The yamin ghamus does not require expiation (kaffarah (definition)) according to the majority of scholars, due to its gravity. Whoever commits such acts must repent to Allah, for Allah forgives sins no matter how great, and the forgiveness of the wronged party does not negate Allah's right.
