To quote from Wikipedia: "It has many standard pronunciations in Modern Standard Arabic, which can also reflect the pronunciation in national varieties of Arabic: IPA(key): [d͡ʒ] in most of the Arabian Peninsula and in Algeria. Also in west Asia where it can be reduced to [ʒ]; IPA(key): [ʒ] in most of the Levant and most of north Africa; IPA(key): [ɡ] in Egypt and west Yemen; IPA(key): [ɟ] in Sudan (with allophones) and south Yemen, and most likely in Classical Arabic. When reciting the Quran, it is customarily pronounced as [d͡ʒ]."
