If money is exchanged in order to get a project, a tender or a contract, it's called bribery or 'rasuah' in plain simple Malay.
Sadly in the lifestyle of Malay muslims (not all of course but quite a norm) who on the surface are getting more religious, this 'rasuah' thing is something they put under the carpet and not discuss.
These people take care of their solats (Alhamdulillah) make sure they only put halal food and drinks in their mouth no mater which corner of the world they are in!
Perform umrah every year and donate to charities (normally 'riakly' announced) and do all other Islamic things.
I met quite a few of these people in London and more so in my beloved country Malaysia.
Rasuah is sinful in any religion! That's why any country and I mean any COUNTRY at all which is corrupt isn't progressive for the longest time.
On a personal level, if you are corrupt, no matter how much money you make, it's never enough! You never feel at peace nor happy within yourself! Bertaubatlah!
