The last few days up until and including the Day of Ashura are the most important because these were the days in which Imam Hussein and his family and followers (including women, children and elderly people) were deprived of water from the 7th onward and on the 10th, Imam Hussain and 72 of his followers were killed by the army of Yazid I at the Battle of Karbala on Yazid’s orders.
