Allâh's Messenger (ﷺ) said, "A man bought a piece of land from another man, and the buyer found an earthenware jar filled with gold in the land. The buyer said to the seller." Take your gold, as I have bought only the land from you, but I have not bought the gold from you. ' The (former) owner of the land said, 'I have sold you the land with everything in it. ' So both of them took their case before a man who asked, 'Do you have children? One of them said, 'I have a boy. ' The other said, 'I have a girl. ' The man said, 'Marry the girl to the boy and spend the money on both of them and give the rest of it in charity. ' [4:678-0.B]
