Hazrat Waleed ibn Jamee’ (may Allah have mercy on him) narrates that a governor of Hazrat Umar ibn Abdul Aziz (may Allah have mercy on him) wrote to him from Yemen that a man was a Jew, then he accepted Islam, then he reverted to Judaism and left Islam. Hazrat Umar (may Allah have mercy on him) wrote back to him: Invite him to Islam. If he accepts Islam, then leave him. If he refuses, then strike him with a stick. If he still refuses, then lay him on a wooden plank and again invite him to Islam. If he still refuses, then tie him up and place the tip of a spear on his chest, then once more invite him to Islam. If he returns (to Islam), then leave him, and if he refuses, then kill him. When the letter arrived, they acted accordingly until the tip of the spear was placed on his chest, then he was invited to Islam, and he accepted Islam, so they left him.
