If this battle had not taken place in Karbala, we would not be aware of the principles of Islam to the extent we are today, and there was probably just a nominal trace of Islam. Not only were this great event and the holy blood of the martyrs not undermined, but they also gained more prominence in history. This is an outstanding example.

Why does Ashura, in contrast to other events in history, gains more vitality over time?

Some events are forgotten over time, like a weak wave created by throwing a pebble in a pool of water– there is a wave, but as the time passes, it becomes weaker every moment and fades away in a short time. But, there are events the other way around; they do not fade away over time; rather, time makes them more prominent. One example is the event of Ashura.
