Cucumis prophetarum is native to Africa and the Middle East, from Mauritania east to the Horn of Africa and southwest to Angola then southeast to South Africa, as well as Israel south to Yemen and Oman and east to northwestern India. It has been introduced to Qatar. It grows wild in semi-desert bushland and grassland up to 6,594 feet (2,010 meters) in elevation, often with acacia trees.

The fruit has a bitter flavor when raw and is sometimes boiled or pickled and the leaves are cooked and served with a staple. The fruit is eaten across its native range and occasionally cultivated and sold in local markets. The fruit is also used in folk medicine in Saudi Arabia to treat liver disorders.
