All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
If your husband intended by this statement to make a promise of divorce and did not intend conditioning the divorce on bringing anything from your parents' house, then divorce does not take effect regardless of whether you brought something from your parents' house for yourself or for your husband, because divorce does not take effect on account of a mere promise of divorce.
However, if his intention was to condition the divorce on a certain action, then the view adopted at Islamweb is that divorce takes effect once the action on which it has been conditioned takes place. This is the view of the majority of the scholars. The criterion in declaring a divorce conditional is the husband's intention while uttering the statement, and not after saying it. If his intention was to prevent you from bringing anything at all from your family (and he conditioned the divorce on that), then divorce takes effect once you bring anything from your family, and his permission after making the oath has no weight in this case. If he meant that you must not bring anything from your parent's house for him and his children (but only for yourself), then divorce does not take effect unless you bring something for him or his children. Please, refer to fatwa 83152.
According to Shaykhul-Islam Ibn Taymiyyah divorce does not take effect if the husband broke his oath, but he must pay an expiation (Kaffaarah) for breaking the oath.
As for the gifts offered to you by your family, you have the right to accept them, and your husband has no right to prevent you from accepting their gifts. However, you do not have the right to accept their gifts for your husband or his children except with his permission.
Allaah knows best.
