(He it is Who hath created you from clay) i.e. from Adam and Adam was created from clay, (and hath decreed a term for you) He created this world and fixed a term for its extinction and made created beings whose lifespan expires with death. (A term is fixed with Him) Allah knows the term of the Hereafter: therein there is no death or evanescence. (Yet still you) O people of Mecca (doubt) in Allah and resurrection after death!
