Hur was the name of one of the high-ranking commanders of the army of Omar-ibn-e-Saad who faced the grandson of the Prophet of Islam Imam Hussain ibn-e-Abi Talib(a.s.), with orders from Yazeed-ibn-Muawiah(l.a.) to either get Hussain(a.s.)'s allegiance for his corrupt Khalifat, or kill Hussain(a.s.) and all his friends. It was Hur and his army who first faced Imam Hussain(a.s.), and then kept them under siege, preventing them from getting water.
On the day of Ashoura, Hur made a huge decision. Right before the battle started, he left his position and the army he was commanding, and joined Imam Hussain(a.s.)
