The Hayah International Academy in Cairo, where Hamdy’s boys are in grades 4, 7 and 11, announced Hamdy’s death to other parents on its Facebook page.
“A devoted and loving mother, Marwa is greatly appreciated by everyone who has had the chance to deal with her,” said the school.
“Her children’s teachers and Hayah parents who know Marwa personally speak of her dedicated and supportive nature; always there to offer a helping hand with a pure smile.”
Mariam Emara posted on her page that she had lost a dear friend.
“Marwa Hamdy she was one of a kind, just a soul and beautiful heart living with us,” Emara wrote.
“I will miss your priceless advice and your kind heart.”
