Aḥmad ibn Muḥammad ibn Ibrāhīm ibn Muḥammad ibn Isḥāq ibn Yazīd

Aḥmad ibn Muḥammad ibn Ibrāhīm ibn Muḥammad ibn Isḥāq ibn Yazīd informed us: This is the book of my grandfather Isḥāq ibn Yazīd. I read in it: Yūsuf ibn Maymūn Abū Khuzayma related to us, from Abū Ḥanīfa—may God have mercy on him—from one of his companions, from Muḥammad ibn al-Ḥanafiyya: The ʿaqīqa existed in the pre-Islamic period; when the Sacrifice came, it was discontinued.

ʿAqīqa denotes the sacrifice associated with a newborn; ‘the Sacrifice’ renders al-aḍḥā. The unnamed transmitter remains unnamed.
