Is it permissible to deliberately break an oath sworn with the ability to fulfill it, given that the reasons for doing so are: not benefiting from the lectures because they are in French, some of them coinciding with prayer times, their non-compulsory nature, and fear of speaking with girls, knowing that the reason for academic failure is not studying at home, and with the utterance of "Insha'Allah" (God willing) at the time of swearing the oath?

If a Muslim takes an oath concerning something and sees that breaking the oath (al-hanth) is better, it is permissible for him to break it and offer expiation for his oath. This is based on the Prophet's (peace be upon him) saying: "Whoever takes an oath and then sees that something else is better than it, let him do that which is better and offer expiation for his oath."

The expiation consists of feeding ten needy persons, or clothing them, or freeing a slave. If one cannot find these, then it is fasting for three days.

As for an oath coupled with the exception "in sha Allah" (God willing), there is no breaking of the oath if the exception was intended before finishing the oath, and no extraneous speech or long silence separated them. The Prophet (peace be upon him) said: "Whoever takes an oath and says, 'in sha Allah,' he has not broken it." It is a condition that the exception be immediately connected to the oath.
