21 – Daʿlaj ibn Aḥmad ibn Daʿlaj ibn ʿAbd al-Raḥmān al-Sijistānī **
The ḥadith scholar, authoritative proof, jurist, and leading imam—Abū Muḥammad al-Sijistānī, later of Baghdad—was a merchant of vast wealth.
He was born in 259 AH, or a little earlier, and after 280 AH he gathered—during his commercial travels—an indescribably large number of narrations in the Two Sanctuaries, Iraq, Khurasan, and the surrounding regions.
