The striker is racing against time to play for Zamalek before the season closes.
Amr Zaki has terminated his deal with Hull City in a bid to feature in Zamalek's remaining games of the season.
The Tigers, who signed Zaki from Zamalek on loan in January, prematurely ended the striker's Premier League adventure after he was hit by a succession of injuries during his short spell at the KC Stadium.
Manager Iain Dowie has made it clear that Zaki would not be able to play with the struggling side in the remaining games of the season, although his loan deal officially expires in June.
The Egypt striker has now stepped up his efforts to terminate the contract and be eligible to take part in Zamalek's Egyptian Cup campaign.
His attempts were fruitful, according to Zamalek's de facto football director, Ibrahim Hassan.
"Everything has been settled with Hull, Zaki is now free," Hassan, the twin brother of head coach Hossam Hassan, said on the club's official website.
"He will be cleared to play with Zamalek once he has received his international transfer certificate."
Zaki's return is likely to hand Hossam Hassan a major boost after he complained about the lack of reliable strikers at his disposal.
Zamalek, who are likely to finish as runners-up to league champions and arch-rivals Ahli, can salvage their season if they win the Egyptian Cup.
They won Egypt's secondary competition in 2008 before enduring a trophy-less 2008-09 season.
The White Knights open their campaign against second tier side Fayoum and are expected to face Ahli in the following round.
