Abdallah served as a delegate to peace negotiations between 33 Darfur tribes in 1989. At the beginning of the Darfur crisis in 2003, he again served as a peace delegate.[2]
In 2007, he was awarded the Robert F. Kennedy Human Rights Award for being "steadfast in his efforts to rectify the region's human rights crisis through serving victims of torture and providing leadership in the movement for peace."[4] The award came with a US$35,000 cash prize as well as a five-year partnership with the U.S.-based organization Physicians for Human Rights.[1] In accepting the prize, Abdallah stated his desire to act not only as a physician, but also a hakim (the Arabic word for doctor):
The role of the Hakim is not only to treat the patients but to protect his community... In Darfur, my role is not just that of a doctor, but someone who must work to protect the community, uphold the human rights of the people of Darfur and work towards peace.[5]
In 2009, Abdallah criticized the policy of U.S. President Barack Obama toward Sudan, stating that though the situation in Darfur was worsening, the U.S. government still lacked a "coherent policy" for the region. Ahmad argued that a regional approach including Chad, Egypt, Libya, and the Central African Republic was the only way to find a long-term solution to the ongoing crisis.[6]
