What is the share of each heir from a sum of 40,000 dinars to be distributed among four brothers and one sister?

The daughter's share is half that of the son, based on the Almighty's saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females."

Thus, the daughter's share would be 4444.44 and the male's share would be 8888.88.
