El-Nahhas will lead Ittihad's training on Monday, the club said in a statement on their social media accounts.
The 46-year-old was dismissed by Arab Contractors last December after a string of poor results saw them drop to the 15th place in the Egyptian Premier League table.
Hossam Hassan was sacked by Ittihad on Saturday, with the team having only claimed three wins in their first 12 games of the season. They sit 11th in the 18-team table on 14 points.
