Found gold coins-How trustworthy are you?

Shamsuddeen Muhammad bin ‘Abdur Raheem Maqdisi was from amongst the outstanding scholars of the seventh century. Once he and his wife, who was also a pious woman, were digging a piece of land at the foot of a mountain for some need of theirs. As they dug they came across a jar full of gold coins. Immediately he recited “Innaa lillaahi …” and covered the coins. Thereafter he told his wife: “This is a test for us from the side of Allah Ta‘ala. It is possible that someone had buried these coins here.” He further took an oath from her that she would not touch it and would not inform anyone of it.”
