Of course...
Of course, such a cause with regard to the Master of Martyrs is more binding than any other Imam because his cause contains that which softens the hearts. It is from this juncture that the Infallible Ones (‘a) used him as their argument whereby they assault their foes.
They, therefore, required their followers to weep, to commemorate in any way, to visit his shrine..., and so on and so forth, causing the umma to become full of the memory of Husayn: Husayni in principle, and to the last breath Husayni... Imam Ja’far as-Sadiq (‘a) recites a special supplication during his prostration that has been transmitted to us by Mu’awiyah Ibn Wahab.
It casts a divine light in the depths of the hearts; it reaffirms the creed; it brings ease to the soul, and it acquaints us with obscure mysteries. The Imam (‘a) used to say the following whenever he prostrated: “Lord!
You are the One Who chose us to receive Your bliss, promised us to intercede, granted us the knowledge of what passed and of what remains, made the hearts of some people lean towards us: I invoke You to forgive me and my brethren and those who visit the gravesite of my grandfather al-Husayn, those who spend their wealth and exhaust themselves out of their desire to express their devotion to us, hoping to earn the rewards which You have for all those who maintain their link with us, and because of the pleasure they bring to Your Prophet, and out of their response to our own order to do so.
Reward them for having vexed our enemy as they sought Your Pleasure. Do reward them, O Lord, on our behalf, and grant them sustenance during the night and the day, and be generous to their families and offspring, those who succeed them in doing such good deeds. Be their Friend; ward off from them the evil of all stubborn tyrants, all those from among Your creatures. Protect their weak from the evil of the mighty ones, be they demons, humans, or jinns.
And grant them the best of what they aspire as they estrange themselves from their home-lands, and for preferring us over their sons, families, and kinsfolk. Lord! Our enemies find fault with their going out to visit our shrines, yet it does not stop them from doing so, unlike those who oppose us. Lord! Have mercy on the faces transformed by the heat of the sun. Have mercy on the cheeks that touch the grave of Abu ‘Abdullah, al-Husayn. Have mercy on the eyes that weep out of kindness to us.
