The word: "Asma," as a proper noun, is derived from what?

Scholars have differed regarding the origin and grammatical measure (wazn) of the name "Asma." Some are of the view that it is derived from "al-wasamah" (beauty/gracefulness), and its initial hamza (ء) is a substitute for a waw (و), with its measure being "fa'laa'." Others believe it is transferred from the plural of "al-ism" (name), with its measure being "af'aal," its initial hamza being extra, and its final hamza being original. Some have gone further, stating that the hamza in it is original, or that it is extra, and its singular form is "ism." The name "Asma" may be used for both masculine and feminine.
