The battle of the Karbala land, started by Ibn Zyad’s army in the order of Yazid. It is written in the history the number of the enemy’s army was more than 20,000 people …. 20,000 against 72….
One of those 72 people was Horr (the commander of Ibn Zyad’s army). He was ordered to stop Imam Hussain (PBUH) and then take him to Yazid but before the battle he found out they were sent there to kill Imam and his family. When the new army of Ibn Zyad joined them and the commander said they are all ordered to kill Imam Hussain (PBUH), Horr doubted. He thought how could he kill the grandson of the prophet, the son of Lady Fatima and Imam Ali (PBUT), how could he kill an Imam who is determined by God?
Finally the light of truth glowed in his heart and he regretted so much. In the morning of the battle, without telling anyone, he ran to the Imam’s camp. He fell to the ground in front of Imam, cried and asked Imam Hussain (PBUH) to forgive him. Imam Hussain forgave him and asked God to forgive him too.
When the enemy attacked, Horr asked Imam Hussain (PBUH) to let him go for the fight as the first one. He got permission and he went to the battle, finally he martyred in the path of truth.
