Is it permissible to take money from the bank account of a deceased man who has no heirs, through a bank employee, in exchange for 50% of the amount, given severe poverty and debt, and considering it a compensation and relief from Allah?

The petitioner has no right to the property of the deceased who has no heir, just like others who are not heirs. It is not permissible for him to resort to trickery or deception to acquire it, especially if a bank employee will share it with him, consuming half of it unlawfully. Determining the absence of heirs requires a precise investigation by the competent authorities.
