Is a mother who died after falling from the fourth floor while doing housework considered a martyr?

The reward of martyrdom is written for those who die outside of battle for several reasons, including: death by abdominal illness, death by collapse (includes car accidents), death by drowning, a woman's death during postpartum bleeding (nifas) or pregnancy, death by burning, death by pleurisy, death by tuberculosis, death by plague, and death in defense of one's religion, property, or self. Also considered a martyr in the sight of Allah is one who falls from mountaintops, or is eaten by wild beasts, or drowns in the sea. These severe deaths are a purification for their sins and an increase in their rewards.
