Is it permissible to copy computer discs, whether Arabic or foreign, if their prices are exorbitant, and does the ruling differ if the device does not work without them?

Computer programs are the property of their owner, and it is not permissible to copy them except with their permission, out of respect for the rights of others. Whether they are expensive or cheap, or whether a device can operate without them or not, has no bearing on the religious ruling.
