The Egyptian Football Association have received a fax from the world governing body, demanding Abd-Rabou's ITC to be given to French club Strasbourg.
"What happened is that FIFA have accepted Strasbourg's appeal," Al-Koumi told FilGoal.com
"The matter has been now taken to the arbitration court and they will announce their decision within 21 days."
The EFA have given Abd-Rabou the green light to participate with Ismaili last month, depending on a letter from FIFA saying that a player involved in a dispute shouldn't be stopped from playing football.
FIFA have initially refused Strasbourg's request to register the player in their squad, but now have made a U-turn and accepted their appeal.
Abd-Rabou played for Ismaili last season on loan from Strasbourg, with an option of a permanent move should the Dervishes pay 500,000 Euros before June 15th.
Ismaili said they paid the fees on time but Strasbourg denied the claim and took the case to FIFA.
