Purchasing pork for a homeless non-Muslim woman

Salam, everyone. Yesterday, while getting groceries, a homeless lady asked me to buy her some sausages. I agreed and waited for her at the checkout. When she came back and scanned the sausages, I noticed they were pork. I didn’t say anything to her in the moment, but after leaving the store, I started worrying if this was haram. I know we’re not supposed to sell or give out anything we can’t consume as halal. Jazakallah khair for your thoughts in advance.
