The charges relate to alleged bribes of $40,000 bin Hammam either paid or offered to 25 Caribbean Football Union (CFU) associations in May during his campaign for the FIFA presidency.
The ethics committee will also hear the cases of Debbie Minguell and Jason Sylvester, the two CFU officials who were also suspended along with FIFA vice-president Jack Warner.
Warner is no longer under investigation following his resignation from football-related activities.
FIFA said in a statement: "The FIFA ethics committee will meet on 22 and 23 July to examine the cases of Mohamed bin Hammam, Debbie Minguell and Jason Sylvester, who were provisionally suspended by the ethics committee on 29 May 2011 in relation to an alleged breach of the FIFA code of ethics and the FIFA disciplinary code.
"The three officials have received the report on the investigations conducted by the ethics committee since 29 May, and have been invited to present their position in writing prior to the meeting of 22 July.
"The hearings with Mohamed bin Hammam, Debbie Minguell and Jason Sylvester will take place on 22 July, when the parties as well as the ethics committee also have the opportunity to call on potential witnesses.
"On 23 July, the ethics committee will deliberate and decide on the cases."
