Is it permissible for the giver of charity to stipulate to the recipient of the charity that they purchase what the giver specifies from a particular place?

A conditional gift has two scenarios:

First: If it is stipulated to the donee that he may not dispose of the gift except according to the condition, then the gift is void, and the donee does not own it.

Second: If the condition is not explicitly stated in the contract, but he says to him: "Take this money and buy such and such with it," then in this case, the donee owns the money and is obliged to dispose of it according to the donor's request. Some have held that if the donor intended a specific purpose, then the money must be disposed of for that purpose. However, if the statement was made in a casual manner, then the donee has the freedom to dispose of it.
