Al-Ma'idah 5:42

The common form of bribe (suht) is that which is taken directly as such. For example, there were ancient religious scholars who used to give false decrees and opinions after taking bribes. However, there is another form of corruption in which there is no direct give-and-take transaction but it is the biggest and worst out of all the various forms of corruption. This is the distorting of the provisions of religion by opportunists to suit popular tastes so that they may have honour and glory conferred upon them by an admiring public, and receive contributions and offerings from all and sundry. Presenting religion in its pure form is always at the cost of unpopularity with the public. On the contrary, a version of religion which without materially disrupting people’s lives, confers the advantages of religion, is very popular and attracts large crowds. The purveyors of a ‘religion’ which does not oblige potential followers to give up or modify their world-oriented lives, and guarantees admission to paradise with the help of some trivial formalities, very soon become the favourites of the public. The same is true of those who present a ‘religion’ which gives sanctity to national and communal interests and all the accompanying frenzy of material activities; which gives a man the opportunity, under the banner of religion, to engage himself in glory-seeking activities.
