No. To do so suggests that you anticipate that guests “must” give gifts and that you are graciously relieving them of that “responsibility.” Gifts are never required, and should never be expected – even to the extent of fending them off, however well-intentioned. While it is kind of you to worry about your guests, it is not your place to tell them how to spend their money. Should anyone ask about giving you gifts, you need merely say, “Oh, no! We haven’t even thought of receiving gifts. We just want you to attend the ceremony and join us in the celebration after.” And, of course, if anyone does give you a gift, you should accept it kindly and follow-up with a gracious thank-you letter.
