It is not permissible
to give the truck owners the mentioned sum, as they have no right to it. They are employed by the farm owners and giving them this money is a means of deception and shows lack of sincerity to the farmer. It also causes harm to others. (Part No. 13; Page No. 129)
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
