What is the meaning of Allāh's Name, "al-Ḥakīm"?

Imām Ibn al-Jawzī (d. 597/1201) summarized the scholars' opinions in his book "Zād al-Masīr" as follows:

1. It means "the Judge". [Ibn Qutaybah]
2. It means "the One who perfects things". [al-Khaṭṭābī]

(Ed: According to al-Ṭabarī and others, it means "The Wise".)
