(a.), a word found in Ḳurʾān, XCVI, 18, usually interpreted by the commentators as the guardians of Hell or else the angels who carry off the souls at death [see malāʾika. 1]. A. Jeffery, The foreign vocabulary of the Qurʾān , Baroda 1938, 148, thought that an origin from Syriac zabūrā , the ductores who, says Ephraim Syrus, lead the departed souls for judgment was likely; but W. Eilers, Iranisches Lehngut im arabischen , in Indo-Iranian Jnal , v (1962), 220, favoured an Iranian etymology, from MP zen ( dān ) bān “warder, keeper of a prison”, NP zindānbān .
