Who is Hagar from The Haj and what is their importance?

Hagar is the first wife of Ibrahim and the mother of Ishmael, Jamil, Omar, Kamal and Nada. She was sent home to her own village soon after Ismael's grandmother died. When she was allowed to return, Ibrahim had taken a second wife. She remains in her husband's household but is sent to work in the market stalls in Lydda and Ramle until they realized that Ramiza could not run the kitchen. She then stayed home to run the kitchen and eventually became close to Ramiza.
