Question 166: What happened to Imam Hussein’s horse (Zuljanah) in Karbala?
Answer 166: The writers of books on what happened on Ashura (these books are referred to as ‘maqatil’) have not mentioned much about what happened to Zuljanah. What is mentioned is that he made his mane bloody with the blood of the Imam and returned to the tents neighing very highly.
When the household of the Imam heard Zuljanah they came out of the tents and found out that the Imam had been martyred. But, some of the later maghatel like Nasekhul-Tawarikh have extended saying that Zuljanah banged his head to the ground so much that he died, some say that Zuljanah had been killed before the martyrdom of Imam Hussain (as) and Imam himself fought against Ubayd Allah ibn Ziyad till has been martyred or that Zuljanah threw himself in the Furat (the river in Karbala that Imam Hussain was denied water from).
