I wouldn't work in construction if its the only way to get a house plan approved is to take a bribe
salamz ukhti,
what you're saying makes sense in theory, but in practice it would be impossible for anyone to build a house, because they know that the architect will have to bribe corrupt officials.
sad situation - can't give anyone an answer on that, nor will anyone bear their burdens on the day of judgement.
but i believe sincerity in making that decision must be there.
and not giving or just giving is not a proper solution.
a solution to this is to absolve oneself of blame before God and help the community by working hard to make sure they stop taking bribes, even if it means getting together more people who want to make that change and demanding a change,
and if that doesn't work, recording the scumbags (spy camera pens video + audio + 8gb memory card capacity are available on ebay for £15).
personally, if i was forced to pay a bribe for something that is my right, i wouldn't feel bad about recording it and paying a decent reporter to publish it.
and if ur in a country where they so openly take bribes, it's highly likely that the press will emphasize ur story for another "payment" - they did for us, they were ready to organize a full press conference with reporters from the top dailies for a certain payment when our land came under dispute and certain government officials had taken payment from the other side.
and if there is injustice right to the top, then to realize that the first solution is to work to establish Islam, and do away with these corrupt criminal governments.
once Islam is established, the rest falls into place as standard procedure.
btw, if the government puts a tax or levy that is not allowed in Islam, it still falls under the same category as injustice - as above, since they are using their position to extract it from you.
