narrated abu huraira (radi-allahu 'anhu):

the prophet (sallallahu 'alaihi wa sallam) said, "allah said: 'the son of adam tells a lie against me, though he hasn't the right to do so. he abuses
me though he hasn't the right to do so. as for his telling a lie against me, it is his saying that i will not recreate him as i created him for the first time. in fact, the first creation was not easier for me than new creation. as for his abusing me, it is his saying that allah has begotten children, while i am the one, the self-sufficient master whom all creatures
need, i beget not, nor was i begotten, and there is none like unto me."
