Is it permissible to claim an injury to receive compensation from an insurance company after a car accident, knowing that the insurance policy is in a friend's name and covers all passengers?

The understanding of the question is that the questioner was not injured, but was with his friend at the time of the accident. If this is the case, it is not permissible for him to claim injury, especially if it leads to a financial entitlement, because it combines lying, deception, breach of trust, and consuming wealth unlawfully. Allah Almighty says: "O you who have believed, do not consume one another's wealth unjustly but only [in lawful] trade by mutual consent." The Prophet, peace and blessings be upon him, said: "Whoever deceives us is not of us, and cunning and deceit are in the Fire."

However, if the questioner was indeed injured and wishes to receive compensation for his injury from the insurance company with which his friend, who caused the accident, contracted, then there is no objection to that, even if the insurance is commercial.
