Is it permissible to purchase camels that have been recommended (for sacrifice) and then donate their value in cash to charities?

If your father endowed his camels or some of them, and their value equals one-third of his wealth, and you were appointed as the supervisor of this endowment, then if the endowment does not grow or yield any return, the fundamental principle of an endowment is that it is not to be sold, gifted, or inherited. Therefore, it is not permissible to sell or exchange it, unless there is a legally recognized interest that necessitates its sale or exchange. The supervisor of the endowment must adhere to the conditions set by the endower. If there is an interest that necessitates its sale, it is not permissible for you to purchase it for yourself, because an agent cannot buy from himself for himself, except under conditions clarified by scholars.
