Unfortunately, the source of all this conflict between the Sunnis and Shia is some major powers that do not want religious unity amongst Muslims.
If Iran is exploiting the ‘Shia factor’ in its foreign policy then it is wrong. But I believe this to be untrue. I visited Lebanon five or six years ago when I was parliamentary speaker during Khatami’s era and we exerted all efforts in preserving the unity between the Sunnis and Shia.
The attempts and propaganda of the enemies, especially those targeting the Islamic Republic of Iran, have so far proved to be futile because the Islamic Republic of Iran has extended the greatest support to the Sunni brethren in Palestine and made every effort to promote unity between Shia and Sunni Muslims in Iraq .
