Brother, Moiz Amjad , you are far more knowledgeable than I am and people listen to you and respect your views. I am keen to learn more about this subject. Regards, The Learner Response Germane brother is a full brother i.e. the same mother and father. Uterine brother is a brother with the same mother but different fathers. Consanguine brother is a brother with the same father but different mothers.
Agnatic brother includes both germane and consanguine brother.
Similarly with sisters. Before I answer your questions, I would like to reiterate one of the points that you have yourself stressed in your letter. I do agree with you that because of the arithmetical ingredients of the problem, it has become a somewhat complicated issue. Nevertheless, I also fully adhere to the fact that if the verses of the Qur an are seen purely from a literal perspective, they present a solution, which is absolutely clear from any complication. However, the fact is that because the solution of the problem actually entails arithmetic calculations of shares some calculated prior to the others there is a potential that if the person has not fully understood the directives of the Qur an, he may commit some errors in the ultimate allocation of the shares of the various parties.
