What is the share of each of the wife, the father, the mother, the two brothers, and the two sisters from the inheritance, and what is the percentage of each of them?

If a person dies leaving only parents, a wife, two brothers, and two sisters, then his mother receives one-sixth due to the presence of siblings, and his wife receives one-fourth due to the absence of any lineal descendants. The remainder goes to the father by virtue of 'asabah (agnatic succession). The brothers and sisters inherit nothing due to the presence of the father, who completely bars them from inheritance. The prevalent view (al-mufta bihi) is that the mother receives one-sixth, contrary to some jurists who hold that she receives one-third if the siblings are barred by the father.
