Is the statement of the guardian, "I marry my daughter to you," and the statement of the husband, "I accept," essential and a condition for the validity of the marriage, or is the father's consent and his presence at the عقد (marriage contract) sufficient, especially since this phrasing is not used in Morocco?

"Marriage is not valid except with the an offer (Ijab) and acceptance (Qabul) according to the majority of jurists, and this is the preferred view. The contract becomes void and must be renewed if these are not present. However, Ibn Taymiyyah holds that marriage is concluded by whatever people customarily consider to be marriage."
