Many examples are given in the Qur'an of corrupt people and their characteristics. Yet the basic attribute of a corrupt person is that they oppose Allah, His messengers and His books, attempt to set up obstacles to the religion and Muslims according to their own vile minds, and reject the limits of Allah. The attributes common to such people are described in the following verse:
As for those who disbelieved and barred access to the way of Allah, We will heap punishment on top of their punishment because of the corruption they brought about. (Surat an-Nahl: 88)
It is mentioned in the Qur'an that these people, who try to prevent others from the way of Allah, disturb peace and harmony on earth, stir up trouble, undermine the commands and prohibitions of Allah, and give short weights and measures. Allah repays these people both in the world and in the Hereafter. He punishes them in many ways as declared in the above verse, and with His endless justice, repays with the punishment due to them everyone who tries to bring corruption.
