‘Ali ibn ‘Usman Hujviri, The Kashf al-mahjúb: The oldest Persian treatise on Súfiism
“ A Gabriel, who worships God so many thousands of years in the hope of gaining a robe of honour, and the honour bestowed on him was that of acting as Muḥammad’s groom on the night of the Ascension—how should he be superior to one who disciplines and mortifies his lower soul by day and night in this world, until God looks on him with favour and grants to him the grace of seeing Himself and delivers him from all distracting thoughts? ”
