I’m currently a niddah and want to buy my husband a Pesach set for Pesach. Am I allowed to give it to him – I know we are not supposed to give gifts but this is something for this festival…
It’s fine to give the gift.
In general, it is permitted, even during the niddah period, to give gifts to one’s spouse (this is ruled by the Kereisi U-Pleisi; the gift should not be of an overly romantic nature).
In this case, the gift is of a general nature (for the home), and therefore there is certainly no problem.
