Hazrat Humaid bin Hilal narrates that Hazrat Mu'adh bin Jabal came to Hazrat Abu Musa while there was a Jewish man with him. He asked: What is the matter with him? He replied: This Jew accepted Islam and then became an apostate, and Hazrat Abu Musa sought his repentance for two months. Upon this, Hazrat Mu'adh said: I will not sit down until I have struck off his neck; it is the decision of Allah and His Messenger (peace be upon him)!
