Saeed narrates that Hazrat Umar (may Allah be pleased with him) wrote something on a shoulder bone regarding the grandfather and the kalalah, then began to seek guidance from Allah Almighty. When he was wounded, he had that bone brought to him and erased it. Then he said: I had written a document about the grandfather and the kalalah, but now I think I should leave you people to your own condition. Thus, people never found out what he had written on the shoulder bone.
