How is retribution exacted from a thief whom the court acquitted, knowing that the stolen money was a trust, three years have passed since the incident, the money has not been returned, and the perpetrator continues to steal from others?

Whoever has had their money seized by force has the right to strive to reclaim it by all lawful means, without transgressing the bounds of Allah. If they do not succeed through lawful methods, then they have no option but to exercise patience and seek recompense from Allah. It is permissible for them to take from the usurper's money an amount equal to their right, based on the Almighty's saying: "And if you punish [an enemy], then punish with an equivalent of that with which you were afflicted" and "The recompense for an evil is an evil like it." However, they must not pursue a path whose harm outweighs the benefit of recovering the money. A trustee is not liable for a trust except in cases of negligence or transgression.
