Prince Nayef bin Abdullah (, al-Amir Nayif ibn ÿAbd AllÃÂh; 14 November 1914 â 12 October 1983) was the younger son of King Abdullah I of Jordan, by his second wife, Suzdil Khanum. As a member of the Hashemite dynasty, the royal family of Jordan since 1921, Nayef was a 39th-generation direct descendant of Muhammad.
Nayef attended Victoria College in Alexandria. He underwent military training in Turkey, being assigned as the honorary Aide-de-Camp of the Turkish President Ismet Inönü from April 1939 until shortly before the outbreak of World War II in September the same year. He became regent of Jordan on 20 July 1951, following the assassination of Abdullah, because his older half-brother King Talal was reportedly suffering from poor health. Nayef ruled in his brother's stead until 6 September 1951, when Talal was judged fit to assume his royal duties. Nayef died in Jordan on 12 October 1983.
