Well, first of all read the exegesis of Surat Nisa 11,12 and 176, secondly, I have an issue as the definitions of, agnates (dadhyal), cognates (nanhyal) elaborate that they are synonyms of consanguinity (blood relation),
in example if a shia die leaving behind father's mother, brother and daughter's son,
according to sunni law the father's mother and brother would be heir but in shia law daughter's son would be heir.
lack of my knowledge is that I have not read any shia jurist so I don't know on which basis they prefer her. even it is clear if the son in law of the demise person is not alive it's mean in past his inheritance has been divided including the wife(who is a daughter of dead man from example) and her son and if he is alive than the daughter's son would be given share twice.

it is very complicated, although law of inheritance is totally very complex esp when you have to compare different school of thoughts, but these type of questions are typically avoided in papers because of strong contradiction and practically a few questions ever asked about law of inheritance in past papers

no no no. firstly by yourself see the past papers, I believe rarely you will find a subjective question with such a complex nature. but its not according to me, If this time paper pattern or paper maker enter any such question. I dont want anyone to stay relax on others observations, so better to first view by yourself. beside the technique of past papers Its my personal observation that law of inheritance is the most difficult chapter both in law and jurisprudence. so most of the time teacher himself try to avoid asking, but if the teacher would be the specialized lawyer of inheritance than one may assume the maximum part would be from it, may we remain safe from such lawyers
