- 1972 Summer Olympics, he went with the Egyptian team to Munich, but was withdrawn by his government after the Munich massacre when members of the Israeli Olympic team were taken hostage and eventually murdered by the Islamic terrorist group Black September.
- 1976 Summer Olympics, after arrival to Montréal, Egypt withdrew from the Games as part of the anti-apartheid boycott. This was due to that in 1972 and 1976 a large number of African countries threatened the IOC with a boycott to force them to ban South Africa and Rhodesia, because of their segregationist regimes. New Zealand was also one of the African boycott targets, due to the "All Blacks" (national rugby team) having toured apartheid-ruled South Africa. The IOC conceded in the first two cases, but refused to ban New Zealand on the grounds that rugby was not an Olympic sport. Fulfilling their threat, twenty African countries were joined by Guyana and Iraq in a Tanzania-led withdrawal from the Montreal Games, after a few of their athletes had already competed. Athletes from Cameroon, Egypt, Morocco, and Tunisia competed on July 18–20 before these nations withdrew from the Games.
