All perfect praise be to Allah, The Lord of The Worlds, and may His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
Forging documents and resorting to fraud in order to get other people`s money is a major sin in Islam, and a Muslim is prohibited from committing such a sin, whether he is in a Muslim or a non-Muslim country.
We advise the person who has committed this act to repent and seek forgiveness, and find a way to give back that money to whom it belongs without causing harm to himself. It is worth warning that it is forbidden to subscribe to non-Islamic/commercial insurance because it is aleatory and involves gambling. For more information on this topic, please refer to Fatwa No. (325). And Allah Knows Best.
