Mujālid narrated—on the authority of al-Shaʿbī—who said: “Judges are four: ʿUmar, ʿAlī, Zayd, and Ibn Masʿūd.” ⦗1⦘
Al-Qāsim ibn Muḥammad reported: “ʿUmar would invariably appoint Zayd as his deputy whenever he set out on a journey.” ⦗2⦘
Sālim said: “We were with Ibn ʿUmar on the day Zayd ibn Thābit passed away, and I exclaimed, ‘Today the scholar of the people has died.’ Ibn ʿUmar replied, ‘May Allah have mercy on him. During ʿUmar’s caliphate he was the scholar of the people and its chief authority. ʿUmar dispersed the other scholars throughout the provinces, forbade them to issue fatwas based on personal opinion, and kept Zayd ibn Thābit in Medina to give legal verdicts to its inhabitants.’” ⦗3⦘
Sulaymān ibn Yasār said: “Neither ʿUmar nor ʿUthmān ever preferred anyone over Zayd in matters of inheritance shares, fatwas, Qurʾān recitation, or judicial decisions.” ⦗4⦘

“To Zayd ibn Thābit, from ʿUmar.”
Khārija ibn Zayd said: “ʿUmar used to leave my father in charge; seldom did he return without granting him a grove of date palms.” ⦗5⦘
