Is a single expiation required for one who has sworn multiple oaths to refrain from watching forbidden things (pornographic films, dancing and nudity videos, pictures of naked women, practicing masturbation, and entering pages that publish nudity), or are multiple expiations required for each oath?

If someone swears to abandon certain things and then commits one of them, and offers expiation for his oath, then commits another of them, he owes another expiation for each subsequent action. However, if he violates all that he swore to abandon before offering expiation, the majority of scholars hold that an expiation is due for each oath. Some scholars, though, are of the opinion that a single expiation suffices. Ibn Qudamah has reported the scholarly disagreement on this issue, noting Abu Bakr's view that one expiation is sufficient. It is recommended to seek Allah's help and offer sincere repentance to abandon sins, rather than relying on oaths.
