Praise be to Allaah.
In Lisaan al-Arab [a famous Arabic-language dictionary], Ibn Manzoor says concerning the root ha-sa-sa: Hissah means a share of food, drink, land, etc. The plural is hisas haassahu means he shared it out, and everyone took his share of it. If you and your husband wish to name your daughter Hessa, there is nothing wrong with doing so. And Allaah knows best.
