The Shabeka Graveyard is in a district south-west of Masjid al-Haram. Prior to the advent of Islam some of the pagan Arabs used to practice the jahiliyyah act of burying their daughters alive, believing them to be a sign of disgrace. It is also said that Sumayyah (رضي الله عنها) is buried here. She was the first person to be martyred in the cause of Islam.
