Don't Curse Caliphs and Other Sahabis

Dear Shia brothers world wide, Please do not curse (لعن) Caliphs and Other Sahabis that are important among Sunni brothers. Our supreme leader, Imam Khamenei, prohibited this and you must know that: 

EVERY CURSE IN YOUR MEETINGS = BEHEADING OF A SHIA MUSLIM IN PAKISTAN, AFGHANISTAN, IRAQ AND SYRIA

Some Takfiris, play recordings of your Majalis in their meetings and at the same time decapitate several Shia Muslims while its playing. So, please don't buy Jahannam for yourself. I heared this statement from an informed source...

We are all Muslims and must respect each others.

ترجمه فارسی:

شیعیان عزیز در سراسر جهان،لطفا خلفای اهل سنت و برخی اصحاب پیامبر را که در نزد اهل سنت محترمند، لعن نکنید. رهبر عزیزمان، آیت الله خامنه ای این امر را حرام کرده اند. خوب است بدانید که :

هر لعنی که شما در مجالس خصوصی و عمومی که ضبط می شود، انجام می دهید = سربریده شدن یک مسلمان شیعه در پاکستان، افغانستان و عراق و سوریه

برخی تکفیریها مثل سپاه صحابه پاکستان، نسخه ضبط شده مجالس برخی مداحان تندرو را در بین جمعیت تکفیریها پخش می کنند و در حین پخش سر شیعیان را می برند، آنقدر که پخش ویدیو تمام شود. دوستان عزیز، جهنم را برای خودتان نخرید. خداوند در قرآن فرموده حتی به بتها و خدایان جعلی کفار دشنام ندهید، چرا که آنها هم به خدا دشنام می دهند. حالا شما چگونه فحش دادن علنی به خلفای اهل سنت و جناب عایشه را حلال می کنید؟ بنده موضوع سپاه صحابه را از یک مسئول رده بالای کشوری شنیدم. لطفا به عقاید و سنتهای یکدیگر احترام بگذاریم و بدانیم که هیچ مسلمان سنی با لعن و نفرین، شیعه نمی شود. 

العربیة:
ایها الشیعة فی العالم، لا تلعنوا الخلفاء الراشدین و الصحابة النبی الذین هم محترمون عند اهل السنة. زعیمنا العزیز، آیة الله خامنئی، یحرّمون هذا الامر. هو الجید لنعرف أن:
لأی اللعن تقولون فی مجالسکم الخاصة والعامة  = الحصول على قطع رأس مسلم شیعی فی باکستان وأفغانستان والعراق وسوریا
یرجى احترام معتقدات کل المسلمین و نعرف أنه لا ینقلب مسلم سنی الی الشیعة، مع لعنة.

Self Flagellation in Shia

Unfortunately some minorities of Shia around the world, specially in Afghanistan, Pakistan and India, mourn in the day of Ashura in Muharram in such a way that no sane person can confirm it. They harm themselves with some type of blades and say that we love Imam Hussein! 

Every year, hundreds of photos of these ceremonies are distributed over the web and if someone, unfamiliar with Shia believes, saw these pictures, he may think: o damn!, what an unconscionable religion!

However, almost all grand Ayatollahs of Shia prohibited these type of mourning. For example, Imam Khamenei, about 20 years ago said:

Tatbir is one of the wrong doings. I know some will say: “It would have been proper if he had not talked about Tatbir.” They will say: “What do you have to do with Tatbir? Some people practice it, let them do so!” No! One cannot remain silent towards such a wrong action.
It is wrong that some people hold daggers and hit themselves on the head to bleed. What are they seeking?! How can this be an act of mourning?! Of course hitting on the head with one’s hands is a sign of mourning. You have seen it several times that when people face suffering, they hit on their chests and heads. This is a typical symbol of mourning. But where have you ever seen a person who is suffering from the loss of a dear one, hit on their head with a dagger and make it bleed?! How can this be a form of mourning?
#Tatbir [#QameZani] is a fabricated tradition. It is among the issues that does not belong to the religion and undoubtedly God is not also pleased with such a practice.
The more I thought about it, the more truly I realized I cannot overlook informing our dear people about Tatbir- which is certainly an act of wrongdoing and a heresy. Do not practice it! I do not approve of it. If someone does something to pretend that they want to practice Tatbir, I will be truly dissatisfied with them. I am declaring this solemnly.
Ayatollah #Khamenei, June 07, 1994
#ImamHussain 

This act, that is well-supported by Western news channels like BBC, CNN and others, is also prohibited in Quran:

And spend in the way of Allah and do not throw [yourselves] with your [own] hands into destruction. And do good; indeed, Allah loves the doers of good.

Shia Beliefs - Five Principles

Twelver Shia Muslims have five principles:

1. Tawhid (توحید): Allah is the only God in the world.
   He is not born of anyone nor gave birth to any one, nor is any one like Him
2. Prophethood (نبوت): Muhammad (PBUH) is the last prophet of Allah.
   Shia Muslims believe in all the Prophets that God has appointed to guide mankind.
3. Imamat (امامت): After the prophet, there are 12 Imams,
   responsible for guidance and leadership of Muslims. They are appointed by Allah.
4. Fairness: Allah is Fair, he doesn’t oppress anyone
   God does not punish people who have obeyed and worshipped him, and does not reward people who have disobeyed Him
   
5. Resurrection: All mankind will be resurrected on the Day of Judgment
   To be judged for their actions and rewarded or punished, depending on each individual’s worldly conduct

What does Shia mean?

In Arabic, the term “Shi'a” originally means one, two or a group of followers. In the Glorious Qur’an, this term is used several times in this sense. For example, God speaks of one of the followers of Moses as one of his Shi'a in the verse (28:15). Elsewhere, Abraham is introduced as a Shi'a of Noah (37:83).

In the beginning of the history of Islam, the term “Shi'a” was used in its original or literal sense for followers of different people. For example, some hadiths speak of the Shi'a of Ali ibn Abi Talib and others of the Shi'a of Mu‘awiyah ibn Abi Sufyan. However, gradually the term acquired a secondary or technical meaning, i.e. the followers of Ali, those who believed in his Imamat (divinely appointed leadership).
