Raya and Sakina (Arabic: ريا وسكينة) were two Egyptian women who were Egypt's most infamous serial killers.

[5] Raya and Sakina's husbands lost their jobs in the cotton industry, and the two couples were becoming increasingly reliant on the brothels that they were running.

This then positioned the other independent workers as the competition, which led the gang of Raya, Sakina, their husbands, and two other men to kill them.

[7] In November of 1920, the remains of a dead woman was found underneath a house in Alexandria while installing running water.

After investigation, it was found that Raya and Sakina had been renting a home beside El Labban police department, where the bodies were buried, at the time when the women and girls disappeared.

[10] The two sisters sold the stolen jewelry to a local jeweler, Ali Hasan, and divided the money among the six criminals.
