Egypt won a 3-0 World Cup qualifying triumph Libya on Monday, which puts them on the brink of winning Group F and reaching the final elimination round.
Ahmed el Fotouh broke the deadlock on 40 minutes, Mostafa Mohamed added a second goal in first-half added time and substitute Ramadan Sobhi netted after 72 minutes.
Egypt have 10 points, four more than second-place Libya, after four rounds and need one win from fixtures against Angola and Gabon in November to be sure of making the play-offs.
The 10 group winners will be split into five pairings, and the winners of the two-legged ties in March will represent Africa at the 2022 World Cup in Qatar.
