The term “Aika” refers to dense, intertwining trees of one or more species of plants that grow together in a single habitat. The Aika may refer to a group of sidr trees, arak tree, athl (tamarisk tree), or palm trees. The Aika (grove) is found in the Arabian Peninsula in the lowlands and valleys. It is called ghaida as well, because water and soil are deposited in it.
The word “Aika” is mentioned 4 times in the Holy Qur’an, and it is always related to the word “companions.” The commentators believe that the companions of “Aika” are the people of the Prophet Shuaib, peace be upon him. God Almighty says: “The companions of Aika (thicket/gove) denied the messengers”. JQ [26: 176] .
