She was especially pleased El Hammamy could now call herself a champion.
"I love her, she is my friend and it's amazing for her and for me to be able to share this happiness with her."
Egypt coach Omar Aziz said it had been hard to motivate the players after the men's and women's tournaments because, with the four top seeds, they had all hoped to win.
"I had to get them back up psychologically. It was step by step, match by match to get here. We didn't talk about the trophy, just the matches."
Egypt has for a long time been the powerhouse in squash and Aziz admitted the bar was high in terms of selections.
"And the production line is always there," Aziz said.
Malaysia coach Andrew Cross felt his players were sluggish early in their matches but had only praise for Egypt and their domination of world squash.
"My girls have done well. We wanted to be in the final so they have done that and I'm proud of how they competed with Egypt, but both (El Araby and El Hammamy) played better today than they did in the individuals final."
