I was invited to attend a Qatari (men's) wedding recently and the groom told me that "as a gift, my presence is more than enough.

And really, during the wedding itself, I haven't noticed anybody with a gift.(may it be Qatari or other nationalities)

I know that it's odd for some cultures to show up in a wedding without any gifts. But it's also odd to some cultures to show up with a gift when it was clearly mentioned not to and if you are the only one with a gift.
