question #2 Sahih al-Bukhari 6626, Book 83, Hadith 6 : How can one make expiation for an oath that should be dissolved?

Allah’s Messenger (ﷺ) said, “Anyone who takes an oath through which his family may be harmed, and insists
on keeping it, he surely commits a sin greater (than that of dissolving his oath). He should rather
compensate for that oath by making expiation.”
