I give you the answer according to the official position: the validity of the passport must expire not earlier than 2 months after the end of the trip. However, there is a recommendation of the Embassy of Egypt in Moscow that the validity of the passport should expire no earlier than 6 months after the end of the trip.

I strongly advise respecting the provisions of visa regimes when going on vacation.

Formally - no. The expiration date of the passport must be at least 6 months from the date of return from Egypt. But there are practically no cases when tourists are not allowed into the country. You must decide whether to go to you or not. You take full responsibility for this matter.
