-Beside the great insight and knowledge of Imam Hussain's companions, one of the important feature of them are the geographical distribution. They were from different tribes of the Arabian Peninsula as well as other countries and cotenants. The wise and knowledgeable people who had gained an accurate understanding of the Imam of their time, had gathered around their Imam from different places, hovered around the candle of their Imam like a butterfly and had sacrificed their lives for him.

-Insight means "the capacity to gain an accurate and deep understanding of someone or something". insight is a power in one's heart that is illuminated by a holy light and by which one perceives the truths just as one sees through the eyes, the faces and appearances of things. Some scholars have said that insight and knowledge are at the heart of religious affairs.

-Imam Husain (a.s) and his companions exhibited the greatest values a persona can achieve. Conversely, their enemies showed the worst vices a person can suffer from.

Examining the material presented by the opponents of the curse of Yazid bin Muawiya, who have doubted the movement of Hussain and his martyrdom in various ways, shows that they have emphasized several main axes: 

1-Regarding the suppression of the Karbala uprising, Yazid, as the rightful caliph of the Muslims, had the right to prevent this danger in any way possible, and he used his ijtihad in this regard 2-The Karbala movement was already doomed to failure

-Yazid is one of the umayyad laders who cannot be forgotten of what he did in Karbala.

Every we should recite the zirayah of Imam Hussein (A.S)
