What is the ruling on the money that a father receives from the social security fund in Germany, after a portion of his mandatory salary was deducted for those insurance payments? Is it lawful (halal)? If it is not lawful, what should the son do?

The question comprises two issues:

1. The ruling on a father benefiting from an insurance fund: If the insurance is commercial or its funds have been invested in usury, then it is not permissible for the father to benefit from it except to the extent of what he himself paid. However, if the insurance is Islamic, he may benefit from it entirely. If the insurance is commercial, the father should be advised not to benefit from it except to the extent of what he paid.

2. The ruling on the questioner eating from his father's money obtained from commercial insurance: This has been detailed previously in Fatwa no. 33204.
