O my masters! O the sons (descendants) of the the Messenger of Allah!
I am your servant, the son of your bondwoman, I yield to you in submission,

I have come to you, seeking refuge with you, moving towards your holy resting place;
I apply to your consideration, and through you seek the divine notice and favour.
May I enter O my masters? May I enter O the dearest friends of Allah?
May I enter O the attentive Angels of Allah, quartered in this place of pilgrimage?
(2) While entering [put the right foot forward] recite:
Allah is the Greatest in His absolute greatness. All praise (in surpassing
abundance) be to Allah. Glory be to Allah in the morning and evening.
Praise be to Allah, the eternally besought, the Majestic, the Single, the Generous, the Bestower of
bounties, the Benefactor, the Compassionate, who did a favour and made easy for me the
"Ziyaarat" of my masters, out of compassion and kindness, and did not stop me from their

(3) It is highly desirable to recite "Ziyaarat Jaami-a'h Kabeer" and "Ziyaarat Ameenallaah",

Peace be on you, O Guides who show the Right Path! Peace be on you,
O the embodiments of piety! Peace be on you, O the manifestations of true

the people to establish justice and fairplay! Peace be on you,
O the personifications of purity! Peace be on you, O descendants of the Messenger
of Allah. Peace be on you, O those who are fully aware of the secret communications!
I bear witness that, verily, you explained the truth and gave sincere advice,
exercised self-control in the way of Allah,
(whenever) people contradicted you and took liberties with you, and had forgiven them.
I bear witness that, verily, you are the rightly guided Guides who show the right path;
verily, it is obligatory to obey you; verily, that which you had said is true.
verily, you invited the people, but they did not pay attention; you gave instructions,
but they did not obey; verily, you are the mainstay of the religion, you maintain the earth,
do not let it depart from Allah's original model, Allah preserved you in the pure
loins, from the beginning to the end, He transferred you from one chaste womb to another,
did not let the dirt of ignorance (even) touch you, did not let the disorder of vain
desires come near you to stir up trouble, purified you [excelled you in knowledge] and thoroughly
cleansed your substance [rendered your source qualified and effective to the highest degree of
perfection], and through you made it possible for us to obtain recompense
on the "day of requital", so, with Allah's consent (all of) you are privileged to glorify
and praise [make known the true meaning of] His attributes, and the blessings we invoke for
you (Salawaat), in fact, becomes a mercy for ourselves. and an atonement of our sins,
because Allah has chosen you for us, refined our nature and manners
through that which He, as a favour, has provided us-our love for you; by knowing you, we, before Allah,
are considered exalted, we are included among those who "profess the true faith" because
we believe in your truthfulness This is the place where one, who has exceeded the bounds and has
done wrong, discovers his own sorry plight, and taking advantage, makes a clean confession and
hopes to obtain salvation, and finally is saved from the danger through you,
and thus the condemned escape the total destruction, Therefore, you are my intercessors,
I have come to you, usually people run away from you, and laugh at the signs of Allah,
treat them with haughtiness.
O He who is Ever-Vigilant, never forgets one thing over another; (who is) Everlasting Eternal,
never passes away the time (free from space-time), surrounds and keeps under control
all things,  (all) bounties belong to Thee, through which, Thou prospers and
assists me, and made me know that (love of Ahlul Bayt) which binds me
securely with Thy bounties, whereas (some of) Thy servants turn aside, and ignore it due to lack of
knowledge, carelessly make light of its obligation, and turn to mediocrity instead of
making use of it (love of Ahlul Bayt); so, do a favour to me and include
me among the special group which stay closely attached with them (the Ahlul Bayt).
(All) praise be to Thou, because I am here, duly thought of and summoned up,
so, do not deny me that which I long for, do not let me fall short of that
for which Thou has invited me, in the name of the sanctity of Muhammad and his pure
descendants; blessings of Allah be on Muhammad and on the children of Muhammad.

  Imam Ja'far ibn Muhammad, the son of the fifth Imam, was born in 83/702. He died in 148/765 according to Shi'ite tradition, poisoned and martyred through the intrigue of the Abbasid caliph Mansur.After the death of his father he beacame Imam by Divine command and decree of those who came before him.

  During the imamate of the sixth Imam greater possibilities and a more favorable climate existed for him to propagate religious teachings.This came about as a result of revolts in Islamic Lands, especially the uprising of the Muswaddah to overthrow the Umayyad caliphate, and the bloody wars which finally led to the fall and extinction of the Umayyads.The greater opportunities for Shi'ite teachings were also a result of the favorable ground the fifth Imam had prepared during the twenty years of his imamate through the propagation of the true teachings of Islam and the sciences of the Household of the Prophet.
The Imam took advantage of the occasion to propagate the religious sciences until the very end of his imamate, which was contemporary with the end of the Umayyad and beginning of the Abbasid caliphates. He instructed many scholars in different fields of the intellectual and transmitted sciences, such as  Zorarah,Muhammad ibn Muslim, Mu'min Taq, Hisham ibn Hakam, Aban ibn Taghlib, Hisham ibn Salim, Hurayz, Hisham Kalbi Nassabah, and Jabir ibn Hayyan, the alchemist.
Even some important Sunni scholars such as Sufyan Thawri, Abu Hanifah,the founder of the Hanafi school of law, Qadhi Sukuni, Qadhi Abu'l-Bakhtari, and others, had the honor of being his students. It is said that his classes and sessions of instruction produced four thousand scholars of hadith and other sciences. The number of traditions preserved from the fifth and sixth Imams is more than all the hadith, that have been recorded from the Prophet and the other ten Imams combined.

  Toward the end of his life the Imam was subjected to severe restrictions placed upon him by the Abbasid caliph Mansur, who ordered such torture and merciless killing of many of the descendants of the Prophet who were Shi'ite that his actions even surpassed the cruelty and heedlessness of the Umayyads.
At his order they were arrested in groups, some thrown into deep and dark prisons and tortured until they died, while others were beheaded or buried alive or placed at the base of or between walls of buildings, and walls were constructed over them.Hisham, the Umayyad caliph, had ordered the sixth Imam to be arrested and brought to Damascus. Later, the Imam was arrested by Saffah, the Abbasid caliph, and brought to Iraq. Finally, Mansur had him arrested again and brought to Samarrah where he had the Imam kept under supervision, was in every way harsh and discourteous to him, and several times thought of killing him. Eventually the Imam was allowed to return to Medina where he spent the rest of his life in hiding, until he was poisoned and martyred through the intrigue of Mansur.Upon hearing the news of the Imam's martyrdom, Mansur wrote to the governor of Medina instructing him to go to the house of the Imam on the pretext of expressing his condolences to the family, to ask for the Imam's will and testament and read it. Whoever was chosen by the Imam as his inheritor and successor should be beheaded on the spot. Of course the aim of Mansur was to put an end to the whole question of the imamate and to Shi'ite aspirations. When the governor of Medina, following orders, read the last will and testament,he saw that the Imam had chosen four people rather than one to administer his last will and testament: the caliph himself, the governor of Medina,'Abdullah Aftah, the Imam's older son, and Musa, his younger son. In this waythe plot of Mansur failed.
