 His brother, Edip Yüksel, is US based lawyer who has become known for converting to and advocating Submitters religion (for which he was rejected by Metin and labeled an apostate by their father).Growing up during the turbulent 1960s and 1970s, a period of near-anarchy and daily bloodshed amongst Turkey's political factions, Yüksel began his activism at an early age.Inspired by the ideas of his father and others, Yüksel quickly became active in the burgeoning political Islam movements that emerged in the early 1950s, following the onset of the multi-party period in 1945.
