The world’s 20 biggest Muslim NGOsMarch 5, 2012
From a 2011 University of Coopenhagen paper by Marie Juul Petersen entitled “For humanity or for the umma? Ideologies of aid in four transnational Muslim NGOs”:
The author of the paper excluded the well-heeled Aga Khan Foundation because that foundation does not describe itself as a Muslim NGO. Italicized organizations are closed because of counter-terrorism prosecution. Budget data comes from 2005 to 2009.
I disagree with some of the amounts and order listed, but overall find this to be a handy, helpful table.
The top organization listed, Islamic Relief, has fallen under increasing disrepute for its work with Hamas and the ties of its leadership to the Muslim Brotherhood. Several of the other charities listed are no better.
