Habib ibn Mohammad al-'Ajami al-Basri, was a Persian [ajami] who settled at Basra. He was a noted traditionist who transmitted from AL-HASAN AL BASRI, Ibn Sirrin, and other authorities. His conversion from a life of ease and self-indulgence was brought about by al-Hasan's eloquence; he was a frequent attendant at his lectures, and became one of his closest associates.

Following from Kashf- al-Mahjub "Unveiling of the Enshrouded" by 'ALI UTHMAN AL-HUJWIRI (Data Sahib) [Source: Kashf al-Mahjub]

His [al-Ajami] conversion (tawbat) was begun by Hasan of Basra. At first he was a usurer and committed all sorts of wickedness, but GOD gave him a sincere repentance, and he learned from Hasan something of the theory and practice of religion. His native tongue was Persian ('ajami) and he could not speak Arabic correctly.
