Abdullah bin Sinaan says that it was Aashoora day when I went to Imam Jafar-e-Sadiq (A.S) and found him in sadness, deep sorrow and grief while his eyes were flowing with tears. I asked him the reason. He said: "don't you know that this was the day when my grand father Syed-ush shuhada Imam Hussain (A.S) was martyred wrongfully". Abdullah asked again: "what should we do today?” Imam told him some aamaal of the day, which are as under:
--- Nobody should engage himself in any work other than mourning and weeping for Imam's museebah and holding majalis;
--- he should not store up the grain etc;
--- Untie his Qaba;
--- Tuck up his sleeves as afflicted, misfortuned (museebat zada) do;
--- (keep Faaqah) Fasting till after Asr time because this was the time when fighting was stopped, and then iftar should be with simple food instead of delicious;
--- Hold majalis to commemorate Imam Hussain (AS)'s martyrdom;
--- Lament, mourn and weep over Imam (AS) as would weep for the dearest son of his own;
--- Recite the Ziarat-e-Aashoora of Imam Hussain (AS); (mafteehul Jinnan may be consulted for Ziarat in Arabic). English ziarat is:
“Peace be on you, O Abu 'Abdillah
Peace be on you, O son of the Messenger of Allah

Peace be upon you, O the chosen one and the son of the chosen one

Peace be on you, O son of the Commander of the Faithful and the son of the chief of the successors.

Peace be on you, O son of Fatima, the leading lady of the worlds

Peace be on you, O fearless warrior of Allah, the one who was killed, but to whom blood revenge is still denied

Peace be on you, and on the souls who died with you.

I send peace of Allah on all of you forever, so long as I remain alive, and the night and day remains.

O Abu Abdillah,

Great is the loss,

And unbearable and great is your tragedy for us, and for all the Muslims,

And unbearable and great is your tragedy in the heavens, and for all the dwellers of the heavens.

May Allah curse the people, who laid down the basis of oppression and wrongs against you, people of the House

May Allah curse those who removed you from your position, and removed you from the rank in which Allah had placed you.

May Allah curse the people who killed you,

And those who facilitated for them the means for your killing

I turn to Allah and to you, away from them,

And from their adherents, their followers, and their friends?

O Abu 'Abdillah,

I am at peace with those who make peace with you,

And I am at war with those who make war with you, till the Day of Judgement.

May Allah curse, the family of Ziyad, and the family of Marwan,

And May Allah curse Bani Umayya entirely,

And May Allah curse Ibn Marjanah

And May Allah curse 'Umar ibne Sa'ad,

And may Allah curse Shimr

And May Allah curse the people who, carried out, saw, and tried to conceal, your killing

My father and mother be sacrificed for you, great is my sorrow for you.

I pray to Allah who has honoured your status, and honoured me through you,

To grant me an opportunity to seek your revenge with a victorious Imam, from the family of Muhammad, blessings of Allah be on him and his family.

O Allah, make me of a worthy status in your eyes, through Hussein, peace be on him, in this world and the Hereafter.

O Abu 'Abdillah,

I seek nearness to Allah,

and to His Messenger,

and to the Commander of the Faithful,

and to Fatima,

and to Hassan,

and to you, through the love and dedication to you

and through disassociating with those who killed you, and prepared to fight you

and disassociating with those who established the foundations of tyranny, and wrongs against you (O Ahlul Bayt).

I turn to Allah, and His Messenger, away from those who laid grounds for it,

and those who built the house of injustice upon it,

and carried out oppression and cruelty, against you and your followers.

I turn to Allah, and to you, away from them,

and seek nearness to Allah, and then to you through love for you and your friends,

and by disassociating with your enemies, and those who went to war with you,

and by disassociating with their adherents and those who follow them.

I am at peace with those who made peace with you,

and I am at war with those who went to war with you.

I befriend those who befriended you

and I am the enemy with those who were your enemies.

I pray to Allah, who has honoured me with awareness of you, and my awareness of your friends

and has enabled me to disassociate from your enemies

(I pray) that He may place me with you in this world and the Hereafter.

And (I Pray) that He may strengthen for me a truthful stance in this world and the Hereafter.

And I pray that He may enable me to reach, your honoured station with Allah

And that He may grant me the opportunity to seek victory, along with a rightly guided Imam from amongst you, who will manifest and speak the, truth.

I ask Allah by your station, and by the honoured position you have with Him,

That He grants me for the grief at your sorrows, more than the personal grief that troubles anyone in tragedy.

What great sorrows (you experienced)! How great was your tragedy, for Islam and in all the Heavens and the earth!

O Allah, make me, at this moment, one who receives from You, blessings, mercy, and forgiveness.

O Allah make me live the life of Muhammad and his family,

and make me die the death of Muhammad and his family.

O Allah, this is a day when Bani Umayya rejoiced, and so too the son of the she who eats the liver of man.

the condemned son of the condemned as said by You, and Your Prophet blessings of Allah be on him and his family,

at every location and occasion in which Your Prophet stood.

O Allah, curse Abu Sufyan, and Muawiya, and Yazid son of Muawiya an everlasting curse

And this is a day when the family of Ziyad was happy, and the family of Marwan because of their murder of Hussein, (blessings of Allah be on him).

O Allah, so increase the curse on them from You, and the painful punishment.

O Allah, I seek nearness to You on this day, and in this position, and for the rest of my life,

through disassociating from them (the enemies) and cursing them,

and though the love of Your Prophet, and his family, peace be on them.

Cursing the enemies of Ahlul Bayt (to be recited 100 times) :

O Allah, curse the first tyrant who oppressed the right of Muhammad and his family,

and the last one who followed him on that.

O Allah, curse the group who fought al-Hussein,

and the group which followed and supported, and joined hands to kill him.

O Allah curse them all.

Salaams on the Martyrs of Karbala :

(to be recited 100 times)

Peace be on You O Abu Abdillah and on the souls that died with you.

Greetings of Peace of Allah be on you, from me, forever so long as I live and so long as the night and day remain.

May Allah not make this my last pledge of your visitation (ziyarat)

Peace be on Hussein,

and on Ali the son of Hussein,

and the companions of Hussein.

Cursing the killers at Karbala :

O Allah, curse particularly the first tyrant

and begin with him first,

and Ibne Marjanah,

and 'Umar ibne Sa'ad,

and Shimr,

and the family of Abu Sufyan,

the family of Ziyad,

and the family of Marwan, till the Day of Judgement.

O Allah, for You is Praise, Praise of those who thank You during tragedy

Praise be to Allah for my intense grief.

O Allah, grant me the intercession of al-Hussein, on the Day of appearance (before You),

and strengthen for me a truthful stand by You, with Hussein and the companions of Hussein,

who sacrificed everything, for Hussein, peace be on him.”
--- Lay curse upon Imam (AS)'s and his companinons' murderers in these words:

"O Allah curse the murderers of Imam Hussain (A.S) and his ashaab (companions)."

"May Allah greaten our reward for we mourn for Imam Hussain alehay salam and cause us and you from among the suitors of his (A.S) blood with His wali Imam Mehdi (Ajja lallaho farajahu) who is from Aal-e-Muhammad (A.S)."

Imam Raza (A.S said: "whoever considers Aashoora day, the day of grief and sorrow, Allah will make the day of resurrection for him, the day of happiness and pleasure."
And then condole Holy Prophet Muhammad (pbuh&hp) Hazrat Ali (AS), Hazrat Fatimah (SA), Hazrat Imam Hasan (AS) and all Masoomeen (AS) for this great museebah while weeping, and then recite the following ziarat:
