He possessed chains of transmission that were higher than those of Baqī. He died in Muḥarram 326 AH, having nearly reached ninety years of age. His father and grandfather were weak narrators, though they were scholars. I am unaware of any criticism levelled at ʿAbd al-Raḥmān—praise belongs to Allah.

95 – Ibn al-Jabbāb, Abū ʿUmar Aḥmad ibn Khālid ibn Yazīd *
The imam, ḥāfiẓ, critic, and foremost muḥaddith of al-Andalus: Abū ʿUmar Aḥmad ibn Khālid ibn Yazīd al-Qurṭubī, known as Ibn al-Jabbāb—a nisbah derived from selling cloaks.

He was born in 246 AH.

He heard hadith from Baqī ibn Makhlad, Muḥammad ibn Waḍḍāḥ, Qāsim ibn Muḥammad, Isḥāq ibn Ibrāhīm al-Dabarī, ʿAlī ibn ʿAbd al-ʿAzīz al-Baghawī, and their peers.

Those who narrated from him include his son Muḥammad, Muḥammad ibn Muḥammad ibn Abī Dulaym (1), the ḥāfiẓ ʿAbd Allāh ibn Muḥammad al-Bājī, and the scholars of Córdoba.

He was one of those unique imams, without equal. Qāḍī ʿIyāḍ said, ‘He was an authority in Mālik’s fiqh.’ In hadith he was beyond dispute, and a great many people narrated from him.
