What is incumbent upon a Muslim whose car overturns, injuring a person and causing paralysis, given that he was not speeding or violating traffic laws, and perhaps suffered a blackout while driving? Is he sinful, and what is incumbent upon him in terms of blood money? Is it acceptable to abide by the state's ruling of one year in prison and payment for all damages?

If the driver took all safety precautions, adhered to traffic laws, was fully conscious, and did not feel anything that would affect his driving, then what occurred was beyond his control, and he is not to be held accountable for it; neither blood money nor expiation is incumbent upon him. However, if he felt a loss of consciousness and continued driving, he is sinful and responsible. If he did not become aware of it until the moment of the accident, he is not to be held accountable. And the ruling of imprisonment and payment for damages is correct if there was negligence on his part; otherwise, it is an injustice.
