Kamel promoted philanthropy. In an interview with Arab News in 2012, Kamel estimated the total value of Islamic zakat in the Kingdom at SR 1 trillion. "Such a huge amount could be used to solve many economic and social problems in the country." He said that people should pay zakat for real estate properties that have been offered for sale. "We Muslims should understand the economic wisdom behind the system if we collect and use zakat properly for it can bring about substantial improvement in our economic conditions. If we had collected zakat from real estate property we would not have faced housing or land problems." He recalled discussing this matter with German Chancellor Angela Merkel. "I can tell you," he said that Islamic economics offers solutions for world problems." Referring to global economic crises he said they would not have occurred if we had implemented an Islamic Hadith by Muhammad which says, "Do not sell what you do not own or possess." In 2010, his son, CEO of DHBC, donated $10 million to Yale University to establish the Abdallah S. Kamel Center for the Study of Islamic Law and Civilization at Yale Law School
