Is it permissible for the agent of a waqf (endowment) for the sacrificial animal (adha) to place the endowment in a joint-stock company in order to sacrifice from its proceeds?

There is no harm in establishing an endowment (waqf) in a joint-stock company that does not deal in usury (riba), provided it is trustworthy and its proceeds are used for sacrifice (udhiyah).
