Is it permissible to sell vowed gold for less than its actual value due to an inability to sell it for its true worth, and out of embarrassment to return it to friends?

This vow must be fulfilled, as it is a vow of an offering. Therefore, the gold must be given in full, and it is not permissible to dispose of it in any way other than what is best for the purpose of the vow. If it was sold for less than its value or a portion of it was gifted, its full value must be paid to the designated recipient of the vow. It is preferable to give the gold itself to those in need or to a charitable organization to distribute it for the benefit of the poor.
