Is it permissible to remove the hijab out of necessity?

The hijab is an obligation that may not be abandoned except in cases of inability or compelling necessity, as Allah the Almighty says: "unless you are compelled to it." Necessity is defined as a person reaching a point where, if they do not commit the forbidden act, they will perish or be close to perishing, or will suffer hardship that is difficult to bear. If a Muslim woman reaches this point, it is permissible for her to remove the hijab to the extent of that necessity.
