Seeing “descendants”
in your dream

Fleas are the soldiers of Allah, which He used to destroy Nimrod 
(descendant of Ham represented in Genesis as a mighty hunter and a king of Shinar), according to Ibn
Siren.
Conversely, the flea symbolizes a mean person who likes to humiliate and stab people. Dreaming of being bitten by a flea 
(or any bug) means one will earn money.
