Genuinely a very tough call. It doesn't look to me like Abouelghar can play the shot without hitting Ibrahim, but it's a close call and I can see the argument for either side.

Clear stroke under the rules of squash. The swing was prevented.

Given the flow of the game, it was clear Abouelghar could have played the shot, not a winning shot, but a shot. Abou was fishing for a stroke.
