following this order, then to the paternal uncles of the grandfather, then their sons, and it remains this way forever. The sons of a higher-level father do not inherit along with the sons of a closer-level father, even if their degree descends, due to what passed in the Hadith. All of this is unanimously agreed upon, by the praise and favor of Allah.
1005 - Issue; he said: (If there is a husband and two parents, the husband is given half, the mother one-third of what remains, and what remains is for the father. If there is a wife and two parents, the wife is given a quarter, the mother one-third of what remains, and what remains is for the father.)
These two issues are called the "Umariyyatayn" (the two issues of Umar), because Umar, may Allah be pleased with him, adjudicated them with this ruling, and he was followed in this by Uthman, Zayd ibn Thabit, and Ibn Mas'ud.

The father here is an agnate (asaba), so he is entitled to what remains after the fixed-share holders, just as if there were a grandfather in his place. The argument would be with him were it not for the established consensus of the Companions in opposition to him, and because...
