Palestine’s campaign ended with a 1-1 draw against Oman after conceding a late penalty in their final group match.
Gradisar, 22, resumed training on Thursday after recovering from a muscle injury sustained during a friendly against Mexican side Pachuca last Sunday.
Ahly, the reigning African champions, are in Group A alongside Inter Miami, Brazil’s Palmeiras, and Portuguese champions Porto in the newly expanded 32-team Club World Cup.
The Cairo-based club will open their campaign on Sunday against Inter Miami at Hard Rock Stadium in Miami.
As part of their preparations, Ahly lost 5-3 on penalties to Pachuca after a 1-1 draw in a friendly earlier this week.
All players are fit and available for selection, according to a team statement on Thursday.
