On one occasion, a person buried some wealth in a certain place for safekeeping, but subsequently forgot where he had buried it. He thus came to Imaam Abu Hanifah (rahimahullah) and laid his complaint before him, asking if he could assist in any way.

Imaam Abu Hanifah (rahimahullah) responded, “Your question is not related to fiqh. Hence, there is no mas’alah for me to work out. Nevertheless, you should go home and perform salaah the entire night until the morning, as you will then remember where you buried your wealth.”
