Hazrat Muhammad bin Yahya bin Haban narrates that Naeem bin Salamah informed me. He had the seal of Hazrat Umar bin Abdul Aziz with him. Hazrat Umar bin Abdul Aziz requested a scroll, and people assumed that this was the same scroll which Hazrat Muhammad (peace be upon him) had written for Hazrat Mu'adh. Hazrat Naeem states that the scroll was read out before you, and I was also present at that time. It was written in it: For thirty cows, one tabi’ jadh’ or jadh’ah is due, and for forty cows, one musinnah is due. Naeem says that I asked, "Tabi’ al-jadh’?" Hazrat Umar replied, "Tabi’ jadh’."
