Thus we find Imām Harb ibn Ismāʿīl al-Kirmānī roaming from land to land, laboring tirelessly in pursuit of knowledge and sparing no effort. One result of that blessed endeavor and outstanding diligence is that he compiled for the Muslim community a large body of important legal questions in various works (1).

[Some of His Teachers]
Imām Harb al-Kirmānī was keen to meet scholars, learn from them, and listen to their ḥadith transmissions; yet he began seeking knowledge somewhat late and therefore did not attain precedence in audition (2).

Among the teachers from whom he transmitted are:
• Aḥmad ibn Muḥammad ibn Ḥanbal al-Shaybānī, Abū ʿAbd Allāh—one of the leading imams, reliable, a ḥadith master, jurist, and authoritative proof, foremost of the tenth generation; he died in 241 AH (3).
• Zayd ibn Yazīd al-Thaqafī, Abū Maʿn al-Raqāshī al-Baṣrī, of the eleventh generation (4).
