In the hadith, he traveled to Tirmidh to meet Abū ʿĪsā in the year 265 AH (1), when he was sixteen years old, having been born in the year 249 AH. He died in the month of Ramadan, on the twenty-seventh of it, in the year 346 AH (2). Al-Ḥāfiẓ Abū Bakr ibn ʿAbd al-Ghanī al-Baghdādī said: His hearings (samāʿāt) are precise and sound, written in the hand of his maternal uncle Abū Bakr al-Aḥwal (3).

We say: The majority of the manuscript copies in our possession are transmitted through his narration from al-Tirmidhī.

2 — The Imām, the ḥāfiẓ, the trustworthy, the great traveler, the man of letters: Abū Saʿīd, al-Haytham ibn Kulayb ibn Sarīj ibn Maʿqil al-Shāshī al-Turkī, author of "al-Musnad al-Kabīr." His origin was from Marw. He traveled to Baghdad, Bukhārā, and Balkh. He died in the year 335 AH (4). We say: He is the transmitter of al-Tirmidhī's "al-Shamāʾil," for through him the book became famous. He also transmitted from him the book "al-Jāmiʿ," as more than one scholar has attributed it to him. Abū Bakr Muḥammad ibn Khayr al-Ishbīlī heard it through his narration, as mentioned in his "Fahrasa," p. 119, and Abū ʿAlī al-Ṣadafī, as in "al-Muʿjam fī Aṣḥāb al-Qāḍī Abī ʿAlī al-Ṣadafī," in the biography of Aḥmad ibn ʿAbd al-Raḥmān ibn ʿĪsā ibn Idrīs al-Tujībī, Abū al-ʿAbbās.
