A Dispute with a Worker over Repairs and His Wages

Question:
He says: A person did some work in my house, and after I paid him part of his due, I found a defect in his work. When he came to ask for the rest, I told him, "Fix the defect and I will give you your due." He refused and left, and I fixed the defect myself. Please advise us on this?

Answer:
This is a matter concerning the courts. This is a dispute that concerns the courts. We advise you to settle this by making a reconciliation with him and giving him his due, or by going to the court. As for judging for yourself, do not judge for yourself. Either reconcile with him, satisfy him, and fear Allah, or deal with him through the court. There is blessing in the court. As for judging for yourself, no; you may be mistaken in your own judgment, and there may be a defect in it. It is obligatory for you to negotiate with him regarding the defect until he agrees to waive part of the wage, or go with him to the court, or give him his due. As for judging for yourself, no.
