The pronoun of affair (ḍamīr al-shaʾn) and pronoun of story (ḍamīr al-qiṣṣah) do not necessarily refer back to an already named individual. Instead, the ensuing clause explains the content suggested by the pronoun. The conventional masculine and feminine labels reflect the two forms.
هِيَ هِنْدٌ مَلِيحَةٌ
The matter is that Hind is beautiful.
Where «هي» is analyzed as the pronoun of story, the following sentence provides its explanation. It should not be confused with an ordinary referential pronoun; the audience is first alerted to an affair that will receive explicit content.
