Is the form of acceptance and proposal mentioned in the presence of a group of men considered a valid marriage contract according to Sharia, and what are the limits of the relationship between the prospective spouses based on it, and is it obligatory to inform the family about it?

We advise the questioner to consult the scholars in their country to examine the circumstances of the matter and determine whether the mentioned words indicate an engagement (khitba) or a valid marriage contract (aqd shar'i). The uncle's statement, "So-and-so came seeking the hand of your esteemed daughter," could imply either an engagement or a marriage proposal. The father's statement, "I accept So-and-so as a husband for my daughter," requires an examination of his intention. We also advise expediting the matter and not delaying the marriage unless there is a clear excuse, and that the father should not seek to annul the engagement, in light of the hadith: "There are three things that should not be delayed: prayer when its time comes, a funeral when it is ready, and a widow (or divorced woman) when she finds a suitable match."
