Announcing marriage even if only in the presence of witnesses only

Q: I seek your Fatwa (legal opinion issued by a qualified Muslim scholar) regarding the ruling on accepting to conclude a marriage contract between a suitor and a Waliy (a legally accountable person acting for a woman regarding marriage) in the presence of four witnesses. This marriage is announced to some people only. Would this announcement suffice? Is the marriage contract valid?

A: If the reality is as you have mentioned, the contract is valid, and the announcement will suffice even if the witnesses are only two people. May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions.
