Is it permissible to take a portion of the money of a Muslim who died in a car accident with his family and has no heir, and what is the ruling on disposing of this money, knowing that if it is not taken, it will go to the bank or to a foreign government?

If a Muslim man, his wife, and his only daughter die in a car accident and have no heirs, their wealth is to be used for the public welfare of Muslims, based on the Prophet's (peace be upon him) saying: "I am the heir of one who has no heir." Public welfare refers to anything whose benefit does not accrue to a specific individual, such as paving roads, building hospitals, and orphanages. It can also be spent on the poor and the needy. The just Muslim ruler or a group of just Muslims are responsible for spending these funds. It is not permissible to receive a portion of this wealth as a gift. However, if the questioner is poor or needy, she may receive a portion of it by virtue of her poverty or need, after confirming that there are no heirs for the deceased.
