carcasses of decomposing carcasses that have been decomposed and wormy
If there is a fly fly which falls in your container then, let him dip the whole body of the fly then let him throw the fly away.
Indeed, in one of the wings of the fly there is medicine and on the other wing there is disease "(Narrated by Bukhari)
Had the carcass of flies with no blood flowing to be judged as unclean, then surely the prophet would not have ordered the fly to be immersed.
Here is the proposition that the carcass of an animal that does not have flowing blood is sacred.
