What is the share of each heir from the deceased's estate, if he left behind: a wife, a full paternal cousin, and two uterine sisters?

If the deceased had no heirs other than those mentioned, then the estate is divided as follows:

To the wife: One-fourth as a prescribed share (fard). To the two sisters from the mother's side: One-third as a prescribed share (fard). To the paternal cousin (son of the paternal uncle): The remainder by way of residuary inheritance ('asaba), based on the Prophet's (peace be upon him) saying: "Give the prescribed shares to those entitled to them, and whatever remains is for the closest male heir."

The estate is to be divided into twelve shares: three for the wife, four for the two sisters, and five for the paternal cousin.
