How is the inheritance calculated if the heirs are: three maternal half-brothers, a wife, and three maternal half-sisters?

If the deceased has no heirs other than the wife and uterine brothers (maternal half-brothers), the inheritance is distributed as follows: The wife receives one-quarter, and the uterine brothers receive one-third, which they divide equally amongst themselves. The remainder goes to the closest male 'asabah (agnate). However, if there is no 'asabah, the remaining portion is returned to the uterine brothers, but not to the wife.
