Ibn al-Qazwini the ascetic (Ali ibn Umar al-Harbi)

أبو الحسن ابن القزويني الزاهد

c. October 970 CE · Muharram 360 AH – c. December 1050 CE · Sha'ban 442 AH

Baghdad's celebrated ascetic — born the night al-Ajurri died (early Muharram 360), 'one of God's great worshippers' who left home only for prayer. His arrival at the Friday mosque in 429 caused such a crush that worshippers rose for prayer by mistake, and from behind the maqsura's screen he declared that the Qur'an is God's speech, disputation an innovation and the mutakallimun astray; he subscribed al-Qadir's creed in the diwan before the jurists. His funeral in Sha'ban 442 closed Baghdad's markets — al-Bardani counted a hundred thousand men; after his death a ten-dinar monthly stipend from al-Salmasi was found recorded 1.

Overview

'Ali ibn 'Umar al-Qazwini, the celebrated ascetic of Baghdad; born at the opening of Muharram 360, he heard Abu Hafs ibn al-Zayyat, Ibn Hayawayh and Ibn Shadhan. Of abundant intelligence among God's righteous servants, he taught Qur'an, transmitted hadith and left his house only for prayer; marvels were related of him. 2

His stance and death

When he entered the mosque on Friday 9 Jumada al-Ula 429 the crowd roared to see him; Ibn al-Madhhab mounted the minbar reading the beatific-vision hadiths, Ibn al-Tamimi refuted him and read the attributes hadiths, whereupon al-Qazwini declared "I hold only that the Qur'an is God's speech, disputation is innovation and the dialecticians astray," and his name was written beneath the Qadiri creed read in the Diwan in 433 ahead of the jurists. He died in Sha'ban 442 — a witnessed day when Baghdad's markets closed — and Abu 'Ali al-Bardani said a hundred thousand attended. 3
