Ya'u and fellow farmer Musa Nasidi managed to escape, but at least 50 people, many of them farmers working their fields at the time, were killed in the attack in the latest in a series of deadly raids on farming areas.
An unknown number of people were abducted in the assault, which was carried out in broad daylight.
Ya'u and Nasidi said the gunmen had attacked their Kankara farming community because farmers had not paid a levy imposed by the armed gang.
Such raids are forcing many farmers to leave their fields, contributing to higher food prices and soaring inflation as Nigeria faces the worst cost of living crisis in a generation.
