What is the share of each heir from the estate of a person who passed away and left behind a mother, a wife, a paternal sister, a maternal sister, and paternal cousins?

The manner of distributing the inheritance cannot be determined until the heirs are definitively identified without any ambiguity. This can be done via the provided link. Paternal cousins (sons of paternal uncles), whether full brothers of the father or half-brothers from the father's side, are among the heirs. However, if they are maternal cousins (sons of maternal uncles), they are not heirs. If the deceased left behind only his mother, his wife, his half-sister from the father's side, his half-sister from the mother's side, and his full paternal cousins or his half-paternal cousins from the father's side, then the mother receives one-sixth, the wife receives one-quarter, the half-sister from the father's side receives one-half, and the half-sister from the mother's side receives one-sixth. The paternal cousins receive nothing because they are residuary heirs (asabah) for whom nothing remains. The issue is an 'awl' (increase in shares beyond the total estate) from twelve to thirteen. The inheritance is divided into thirteen shares: the mother receives two shares, the wife receives three shares, the half-sister from the father's side receives six shares, and the half-sister from the mother's side receives two shares.
