Why can females not be named with compound names formed from one of the Most Beautiful Names of Allah, or from another attribute like "Najm al-Din" (Star of the Religion) and its equivalents, as is the case when naming males?

There is nothing in Islamic law to prevent naming women with compound names. This naming practice was well-known during the era of the Tabi'in and those who came after them, without objection from the people of knowledge. Examples include: "Amat al-Rahman" bint Abi Bakr ibn Hazm, and "Shajar al-Durr," as well as women named "Sitt al-Fuqaha" (Mistress of Jurists), "Sitt al-Khutaba" (Mistress of Orators), "Sitt al-Ulama" (Mistress of Scholars), and "Sitt al-Arab" (Mistress of Arabs). Furthermore, the naming with "Amat Allah" (Handmaiden of Allah) is common, such as Amat Allah bint Hamza, and Amat Allah bint Razina, the freed slave of the Messenger of Allah, peace and blessings be upon him.
