Is a marriage concluded by the recitation of Al-Fatiha, acceptance, and public declaration, without a formal legal contract or a guardian (wali), considered Islamically valid, and does it entail divorce in the event of separation?

Marriage is a great ritual that has conditions for its validity, the most important of which are the guardian (wali) and witnesses. The aforementioned marriage is invalid due to the absence of these two conditions, and it requires divorce (talaq) or annulment (faskh). In case of dispute, the Sharia court or the Muslim community must be consulted to resolve the disagreement.
