The Center of Mosque Studies - This year's Arbaeen of Karbala was an astonishing event. The enemies of Islam and Ahlul Bayt vainly thought that they had blocked the path of Muslims. Notice what a great movement was launched. When even bodies stay together, it has such a reflection. If we stay together, if Islamic governments and Muslim nations - whether Shia or Sunni or different denominations of Shia and Sunni - are honest with one another, if they are not suspicious of one another, if they do not insult and have malevolent intentions against one another, notice what will happen in the world and what great dignity will be brought about for Islam. Unity, unity!
Today, some elements both among Sunnis and Shias are working at separating Muslims from one another. If you trace these elements, you will see that all of them are connected to espionage and intelligence services of the enemies of Islam - not the enemies of Iran and Shia Muslims, rather the enemies of Islam. The kind of Shia which works with the MI6 of England and the kind of Sunni which is a mercenary of the CIA of America are neither Shia nor Sunni. Both of them are against Islam. It is 35 years now that we in the Islamic Republic are letting out this cry. We do not only speak, rather we act. The Islamic Republic's assistance to its Muslim brothers has mostly been given to Sunnis. We have stood beside the Palestinians. We have stood beside the religious people of regional countries because we know that today, the issue of unity is at the top of Islamic issues.
