What is incumbent upon me regarding the damages to the car and the injuries to its occupants resulting from an accident caused by me, knowing that the accident led to fractures and injuries for my colleague's children, and damages to the car, in addition to its diminished value after repair?

The questioner must guarantee what he has damaged and compensate the injured parties if they do not forgive him, because whoever consumes or damages another's property, whether directly or indirectly, guarantees it, whether intentionally or by mistake, and whether mature or immature. The texts of Islamic law indicate the legitimacy of compensation for damages. The Sharia (definition) judge estimates compensation for damages and the equitable indemnity for crimes for which Islamic law has not specified a fixed amount. Compensation may include the costs of medicine and the doctor's fees.
