What is the ruling on working as a truck driver transporting building materials that are purchased by those who take out usurious loans to build homes in a city where usurious loans are widespread?

Renting out services for the transport of household goods and other items is permissible if the benefit derived from them is Islamically lawful. There is no objection to transporting these materials for individuals who deal in usury, even if they purchased them with an interest-based loan, because the transporter has no connection to the loan, and his wage is lawful in exchange for his permissible work. Muslims engage in buying, selling, and renting with those who deal in usury, even though they know their money is intermingled. Indeed, Ali (may Allah be pleased with him) worked for a Jew who engaged in usury.
