Hosni Abd-Rabou signed a two-year deal with Zamalek SC.
Zamalek will pay the midfielder LE 6,500,000 per season.
The 28-year-old signed a three-year deal with Ismaily last summer but said he could cancel his contract after Ismaily failed to pay him 90% of his money.
According to the player, his new contract with Ismaily could be terminated if the club failed to pay his financial dues before 18 August 2011.
Zamalek is waiting for the termination of his contract with Ismaily to complete the deal.
