The pinnacle of earthly bliss was reached when Adam and Eve witnessed the birth of their first children, a set of twins. Adam was a devoted father and Eve a contented mother. The twins were Cain (Qabil) and his sister. Later Eve gave birth to a second set of twins, Abel (Habil) and his sister. The family enjoyed the bounties and fruits of the earth provided by their Lord. The children grew up to be strong and healthy young adults. Cain tilled the land, while Abel raised cattle.
