[1][2][3][4] He became widely known as an activist after launching several street art campaigns that criticized the political situation in his country and the conflicts which broke out in 2015 in Yemen.

[1][9] In the spring of 2011, specifically with the start of the peaceful Yemeni revolution, Murad was one of earliest to join the protestors in their demand of a just, civil state.

[3][12][14][16][17] This campaign lasted for three months of which artists, passers-by, elders, children, men, women and even soldiers painted alongside him in different areas in Sana'a city.

He called the campaign "The Walls Remember Their Faces" on September 8, 2012, to highlight the forcibly disappearance of political activists and journalists from the late 1960s and until 2011.

He used stencil technique to paint the faces of the forcibly disappeared on the walls of the cities and invited their families and people in general to join him.

[1][3][6] Subay and his friends painted the pictures of 102 forcibly disappeared victims in many areas in the cities Sana'a, Taiz, Alhudayda and Ibb.

[4][6] On July 4, 2013, Subay launched the third campaign "12 Hours" to discuss 12 political and social issues affecting the Yemeni society and led it off with a mural about spread of weapons.

Subay was meaning to continue working on this campaign, had it not for the power outages and lack of funding that forced him to postpone the activity.

Subay painted his first mural in the campaign in an area called "Bani Hawat" located in the suburbs of Sana'a, where an airstrike killed almost 27 civilians, including 15 children.

[7][14][29][30] His friends began to join him during the second activity of the campaign, in an area called "Faj Attan", a heavily populated area inside the capital Sana'a where a heavy air strike on a weapons storage facility nearby left behind tens of killed and injured civilians and destroyed the homes of hundreds of people.

[14] Subay painted the seventh mural in London, where he discussed the ignoring of international community and media of the conflicts in Yemen.

They painted the murals in front of Yemen Central Bank after the value of Yemeni Rial against the US Dollar dropped significantly, adding another misfortune to the already impoverished nation.

He invited people to the event to express their love for life, beauty, homeland, and their fear of an expected civil war.
