Overview
Aclima (also Kalmana, Lusia, Cainan, Luluwa, or Awan) according to some religious traditions was the oldest daughter of Adam and Eve, the sister (in many sources, the twin sister) of Cain. This would make her the first female human who was born naturally.
states that after he had killed Abel, "Cain knew his wife, and she conceived and bore Enoch". In an effort to explain where Cain and Abel acquired wives, some traditional sources stated that each child of Adam and Eve was born with a twin who became their mate.
Aclima and Lusia
In Muslim tradition, Cain was born with a twin sister who was named Aclima, and Abel with a twin sister named Jumella. Adam wished Cain to marry Abel's twin sister, and Abel to marry Cain's. Cain would not consent to this arrangement, and Adam proposed to refer the question to God by means of a sacrifice. God rejected Cain's sacrifice to signify his disapproval of his marriage with Aclima, his twin sister, and Cain slew his brother in a fit of jealousy.
In another Muslim tradition, Cain's twin sister was named Lusia, while Aclima was Abel's twin sister.
