The Court of Arbitration for Sport (CAS) announced the verdict on Tuesday, but said the ban will take affect starting from next season.
This means that Al-Hadari is eligible to play for the rest of Ismaili's Egyptian Cup campaign.
The CAS also imposed a $800,000 against Sion for their part in the breach of Al-Hadari's contract with Ahli.
The Swiss club were also banned from recruiting any new players in the next two transfer periods.
