أبا يعقوب الغزال

I heard Abū Yaʿqūb al-Ghazzāl say: I heard Muḥammad ibn ʿAlī ibn al-Munīr say: Ibrāhīm ibn al-Ashʿath informed me, saying: I heard al-Fuḍayl say: Abū Yūsuf said—and Abū Yūsuf spoke truthfully—“Only someone who is unconcerned with this world and concerned with the next can pursue this matter to the fullest.” [Meaning the study of jurisprudence.]
