Halhāl (Arabic: الهلهال بن المحول) is the sword-bearer of Iblis. When he came to King Sulaiman he appeared in a as it were of smoke, and burning fire came out of his mouth. Fresh blood dripping from his hair on to his body and by his side hung a sword and knife. The king asked him: "Who art thou?" He answered, "I am Halhal, the sword-bearer of Iblis." The king asked him: "What is thy work?" He answered: "Not a drop of man's blood is shed on earth except through me, and this chain which thou seest upon my neck is of the blood of Habil." The king commanded him to be bound, but he said: "Fetter me not, O Prophet of Allah! I will assemble for thee all the giants upon earth, and will make thee a sure promise that I will do no hurt as long as thou livest." Then the king set his seal upon his neck and let him go free; and he became obedient to Sulaiman.
