 If you want to know about the greatness of Imam Al-Hussein, see how the entire universe interacted with his martyrdom. The entire universe cries for Imam Al-Hussein. When you cry on Imam Al-Hussein, you need to realize that this is not some isolated event that you, as a human being, you're simply crying. When you cry on Imam Al-Hussein, you are participating in a universal event, in an event that the entire universe participates in. Imam Al-Sadiq, in the first visit of Imam Al-Hussein, al-Mufatih Al-Junan, what does he say? He says, and the entire universe, the earth and the seven heavens, they cried for Imam Al-Hussein, al-Salam. Every creation of Allah, subhanahu wa ta'ala, cried for Imam Al-Hussein, al-Salam. And let me tell you more, even the inhabitants of hell, they cry for Imam Al-Hussein, al-Salam. According to the words of our sixth Imam of Ahlul Bayt. Now, you may wonder how is it that the people of hellfire cry for the Imam, al-Salam. First of all, it could be that Allah, subhanahu wa ta'ala, shows them the truth about the Imam, al-Salam. And even the most evil of the evil, when they see what happened to Imam Al-Hussein and the greatness of Imam Al-Hussein, they'll cry for him. Didn't Muawiyah cry on Imam Ali ibn Abi Talib, al-Salam, when Zaraar described to him the qualities of Imam Ali to the point where Muawiyah's beard was soaked with tears? Who in history do you see their enemies cry on them like that? Other than the Ahlul Bayt of the Holy Prophet, peace be upon him. Even the inhabitants of hell shall cry for the Imam, al-Salam. Secondly, everything in its existence cries for the Imam because the Holy Qur'an tells us everything in existence glorifies God, has a level, a degree of perception. وَإِمْ مِنْ شَيْئِنْ إِلَّا يُسبِّحُ بِحَمْدِهِ وَلَا كِنْ لَا تَفْقَهُنَ تَسْبِحَهُمْ The Qur'an says everything in God's creation has some perception. It glorifies Allah, subhanahu wa ta'ala, but you people, you do not understand that, you do not see that. You cannot hear them glorifying Allah, subhanahu wa ta'ala. Therefore even the inhabitants of hell, their very existence, every cell in their body cries for Imam al-Husayn, alaihi s-salam. Imam Zayn al-'Abideen, peace be upon him, when he stood before Yazid ibn Muawiyah in Sham, you've heard the story of his speech and how Yazid called on the Mu'addin to cut off the speech of Imam Zayn al-'Abideen. When the Mu'addin said, اشهدوا الله إلا الله What did Imam Zayn al-'Abideen alaihi s-salam say? The Imam alaihi s-salam says, not only do I bear witness that there is no God but Allah, but every cell in my body, my blood, my flesh, my hair, my bones, they all bear witness that there is no God but Allah. The existence that Allah, subhanahu wa ta'ala, has created cries on Imam Abi Abdullah al-Husayn for that tragedy. The skies wept blood for the tragedy of Imam al-Husayn. And those of you who might think, how is that possible? Isn't this an exaggeration to say that the skies wept blood for the Imam alaihi s-salam? Well, when you refer to the Holy Quran, Surah al-Dukhan, what does Allah, subhanahu wa ta'ala, state? فما بكت عليهم السماء Allah, subhanahu wa ta'ala, in speaking about the evil ones, the Pharaoh and his people, Allah, subhanahu wa ta'ala, drowned them. Allah, subhanahu wa ta'ala, punished them. Then the Quran says, the skies did not weep for them. The skies did not cry for them. I ask you, if it's impossible for the skies to cry, why does Allah, subhanahu wa ta'ala, say that the skies did not weep for the Pharaoh and his people? If it's impossible, then this would be unwise for Allah, subhanahu wa ta'ala, to say in the Holy Quran. If it's impossible for the skies to cry on anyone, then why did Allah say, the skies did not weep for Pharaoh and his people? We have tens of narrations from the books of our Sunni brothers that tell us when Imam al-Hussein alaihi s-salam was killed, the skies wept and rained blood because of what happened to the Imam alaihi s-salam. This is one small glimpse of the Imam, peace be upon him.
