Khomeini believed in Muslim unity and solidarity and the export of his revolution throughout the world. He believed Shia and (the significantly more numerous) Sunni Muslims should be “united and stand firmly against Western and arrogant powers. “Establishing the Islamic state world-wide belong to the great goals of the revolution.”[131] He declared the birth week of Muhammad (the week between 12th to 17th of Rabi’ al-awwal) as the Unity week. Then he declared the last Friday of Ramadan as International Day of Quds in 1981.
