Hajjāj ibn al-Shāʿir, and Muḥammad ibn Ḥassān al-Azraq, Muḥammad ibn ʿAbd al-Malik ibn Zanjuyah, Ibrāhīm al-Muzanī, al-Rabīʿ ibn Sulaymān the muezzin, Bahr ibn Naṣr, Saʿdān ibn Naṣr, al-Ramādī, Abū Zurʿa, Ibn Wārah, and a host of scholars of their generation, along with many who came after them in the Hijaz, Iraq, Persia, Egypt, Syria, the Jazīrah, and the mountain regions.
