His full name is Abu Abdullah Harith bin Asad al-Basri. He was born in Basra in 781.1It was his characteristic property.2 He was a founder of Sufi doctrine, and influenced many subsequent theologians, such as al-Ghazali . He wrote many books about theology and Tasawwuf (Sufism), among them Kitab al-Khalwa and Kitab al-Ri`aya li-huquq Allah ("Guarding God's Rights").3In al-Khalwa , in a discourse on fear and hope: Know that the first thing that corrects you and helps you correct others is renouncing this world. But you will find your soul worthier of honour by ridiculing this world. This world is abhorred of God almighty and the messengers. It is an abode of afflication and a station of foolishness.4Be on your guard from it. al-Khalwa' s argument elsewhere cites al-Hasan al-Basri.5The above pericope was later transplanted into a fictional response by al-Hasan to 'Umar b. 'Abd al-Aziz. Translated in Suleiman Ali Mourad, Early Islam between myth and history (Brill, 2006), 128; from Khalwa , 24. Mourad 128-9 cites Ibn Abi'l-Dunya, Dhamm al-dunya , 146 #341; Ibn al-'Arabi quotes from that.6
