Is it permissible for a Muslim to attend a wedding, accept the invitation to dinner at its beginning, and then leave before the music starts playing?

If the situation is as described, it is permissible to attend the wedding feast for dinner, then leave before any reprehensible acts, such as playing music, occur. It is not permissible to continue attending after the music starts, as we have mentioned the impermissibility of remaining at weddings where reprehensible acts like musical instruments are present.
