He was also known as ʿAlī ibn Abī Ḥāmid al-Kharjānī.
Kharjān is pronounced with an open khāʾ.
He passed away in 420 AH, though some say in 421 AH at Burāb.
One of his reports reaches us in the Forty Ḥadith collection of al-Raʾīs al-Thaqafī narrated from him.

From among his contemporaries:

276 – Abū al-Ḥasan ʿAlī ibn Muḥammad ibn Aḥmad al-Jurjānī—spelled with two jīm’s—known as al-Ḥannāṭī, the schoolteacher.
He related hadith from Abū Aḥmad ibn ʿAdī and others, and he lived on until roughly 420 AH.
I mention him only for the sake of distinction; he was also called Ibn ʿArafa.

277 – al-Kharaqānī, Abū al-Ḥasan ʿAlī ibn Aḥmad al-Bisṭāmī, the ascetic and exemplar. Abū al-Ḥasan ʿAlī ibn Aḥmad al-Kharaqānī, al-Bisṭāmī, hailed from the village of Kharaqān, the middle letter being vocalised (1).

Al-Samʿānī said: “He was the shaykh of the age, endowed with miraculous gifts and spiritual states. He used to earn his keep by hiring out a pack-animal, until divine openings were granted to him. Maḥmūd ibn Subuktakīn visited him; he admonished him and would not accept anything from him.” (2)
