What is the ruling concerning the action of a person who invested endowment funds designated for the service of the Holy Quran in land trading, which led to an increase in the money, then its value decreased due to stagnation, and he did not inform the supervisor of the endowment about this? And what is incumbent upon him and upon the supervisor of the endowment?

It is permissible to invest the surplus from the endowment's revenue, provided that the investment is lawful and adheres to Sharia and commercial regulations, such as preserving the endowment's principal, developing its assets, avoiding high risks, and disclosing investment operations. The conditions set by the endower must be observed in this regard. If the investment has been carried out according to these regulations, then there is no harm in it. The trustee is entrusted unless there is an act of transgression or negligence on their part. It is preferable to present such matters to the competent authorities or scholars.
