Mansūr ibn ʿImrān ibn Rabīʿah al-Rabāʿī, from Wāsiṭ, better known as Ibn al-Bāqillānī.

He was born at the very beginning of the year 500 AH.

He mastered the Ten Canonical Readings under Abū al-ʿIzz al-Qalansī, ʿAlī ibn ʿAlī ibn Shīrān, and Sibt al-Khayyāṭ.

He also received ḥadīth from Khamīs al-Ḥawzī, Abū ʿAbd Allāh al-Bāriʿ, Hibat Allāh ibn al-Ḥuṣayn, Abū al-ʿIzz ibn Kādis, Abū ʿAlī al-Fāriqī, Abū Bakr al-Mazrafī, Abū al-Karam Naṣr Allāh ibn al-Jalakht, and a number of others.

Among those who narrated from him were al-Samʿānī (1) and Ibn ʿAsākir (2), the latter transmitting some of his devotional odes. He was, in fact, an accomplished poet.

Those who reported ḥadīth from him and recited the Ten Readings to him include: Taqiyy ibn Bāsūyah, al-Murajjā ibn Shaqīrah, Abū ʿAbd Allāh ibn al-Dubaythī, al-Ḥusayn ibn Abī al-Ḥasan ibn Thābit al-Ṭībī, Imām Abū al-Faraj Ibn al-Jawzī, his son Muḥyī al-Dīn Yūsuf, al-Sharīf al-Dāʿī, and many who journeyed from distant lands in search of his elevated chain of transmission.
