Narrated Abu Huraira: Allah's Apostle said, A man bought a piece of and 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.'
