Gourds refer to creeper Cucurbitales that are usually edible. Dry gourds from which the pulp is removed have been used for fishing, swimming and diving purposes, as these dry fruits float on water. Maybe this plant spread in numerous places worldwide due to its ability to float and swim on water.
Gourds are mentioned once in the Quran. It was the plant Allah made to grow above Prophet Younus, peace be upon him, after He brought him out of the belly of the great fish. Allah Almighty says about that: “And We caused to grow up for him a gourdplant.” [Al-Saffat: 146]
