Is a marriage contracted in Belgium in the presence of the family, the brother, and the brother-in-law as witnesses valid and permissible for consummation, given the father's knowledge and acceptance of the contract despite his absence from it?

For a brother's testimony in a marriage contract to be accepted, he must not be the one who officiated it; if he officiated it, his testimony is not accepted. The testimony is completed by the presence of two just witnesses from those present, and it is a condition for a witness to be a Muslim, male, and just.
