On the way his path was blocked by the forces of Yazid. This army consisted of a thousand men. When they reached the caravan of Husayn (a.s) they were dying of thirst as their water supply had been exhausted. The riders’ condition was serious due to the thirst. The horses were hanging out their tongues. It was the army of foes but the son of the great Prophet of Mercy could never allow them to perish of thirst. He ordered that not only the men buts their beasts also be provided ample water.
