The National Emblem of Iran since the Iranian Revolution features four curves and a sword, surmounted by a shadda. It is very similar to the Sikh Khanda symbol. The emblem was designed by Hamid Nadimi, and was officially approved by Ayatollah Ruhollah Khomeini, the first supreme leader of Iran, on 9 May 1980.

The national flag of the Islamic Republic of Iran, also known as the tricolor, is a tricolor featuring the Pan-Iranian colors comprising equal horizontal bands of green, white and red with the national emblem ("Allah") in red centred on the white band and the takbir written 11 times each in the Kufic script in white, at the bottom of the green and the top of the red band. After the Iranian Revolution of 1979, the present-day flag was adopted on 29 July 1980.
