Absh is an Arabic and Farsi word that means mobilization, gathering, when an army becomes mobilized and ready to fight. That's the only word close to Abish that I can find.
Abish is also a Christian (Mormon) female name mentioned in the Book of Mormon. It is also seemingly Hindu name. It may also have a meaning in Urdu. I couldn't find any trustworthy information on its meaning. If the meaning is good you can use it.
