Sheikh Shems or Melek Shams ad-Din is a holy figure venerated in Yazidism, he is considered one of the Seven Divine Beings, to all of whom God assigned the World's affairs, and his earthly incarnation is considered one of the four sons of Ezdina Mir along with Nasirdîn, Fexredîn, and Sicadîn, who are the respective ancestors and patriarchs of the four Şemsanî Sheikh lineages.

Yazidism, also known as Sharfadin, is a monotheistic ethnic religion that originated in Kurdistan and has roots in a western Iranic pre-Zoroastrian religion directly derived from the Indo-Iranian tradition. It is followed by the mainly Kurdish-speaking Yazidis and is based on belief in one God who created the world and entrusted it into the care of seven Holy Beings, known as Angels. Preeminent among these Angels is Tawûsî Melek, who is the leader of the Angels and who has authority over the world.
