What is meant here by "and when he tawallā"?

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

1. "Becomes angry" [Reported from Ibn ʿAbbās and Ibn Jurayj]
2. "Turns away from the statement he made" [al-Ḥasan]
3. "Gains authority," derived from the word wilāyah [Mujāhid, al-Ḍaḥḥāk]
4. "Turns away physically" [Muqātil, Ibn Qutaybah]
