Is it permissible to benefit from discounts and offers provided on the occasion of holidays such as "Mother's Day" or "Valentine's Day," knowing that these holidays are not celebrated?

There is no objection to purchasing permissible offers during the holidays of disbelievers due to their reduced prices, provided that it is not for the purpose of celebrating with them. This is because accepting a gift from disbelievers on their holiday is permissible, and purchasing from them is even more so. Ali ibn Abi Talib accepted a gift on Nowruz, and Aisha permitted eating from the trees of the Majus during their holiday, but not from their slaughtered animals. Abu Barzah would accept their fruits but refuse other things. This indicates that the holiday does not prevent accepting their gifts, and the ruling regarding their gifts is the same whether it is during their holiday or not, because there is no assistance to them in their rituals of disbelief. It is permissible to eat the food of the People of the Book on their holidays, whether purchased or gifted, as long as it was not slaughtered for the holiday. As for celebrating Valentine's Day and Mother's Day, these are innovations and newly invented matters.
