Is a bribe paid for Islamic banking facilities Islamic?

Dear Mufti Johor (the man who passed a decree against Santa Claus hats), when the Chairman of Bank Rakyat takes a bribe of RM1,280,000 to approve Islamic banking facilities for the construction of a hospital in Shah Alam (that the company linked to the Sultan of Selangor’s family has now abandoned) is the bribe Islamic or un-Islamic?
