The Qatari was given the ban by FIFA's ethics committee two weeks ago after being found guilty of paying or offering bribes.
Bin Hammam cannot formally lodge an appeal until the reasoned decisions have been produced by FIFA and he claims the "delay is suspicious".
He said in a statement: "Although FIFA was keen to introduce the sanctions against me immediately, it has been in much less of a hurry to publish the reasons behind its decision.
"This delay is suspicious in that it gives FIFA the time to devise a justification for a decision that it was always going to make anyway. This is also outrageous as FIFA has been quick to publicise my guilt while holding up my opportunity to appeal.
"FIFA is therefore violating its own rules by seeking to enforce an order before issuing a decision explaining its grounds.
"I therefore call on FIFA to produce its reasoned decision as soon as possible and I also renew the request that was made on July 23 to release a full transcript of the hearing to the media, for the sake of transparency."
