Referring to the verse: "Those who believed and adopted exile... As to those who believed but came not into exile": A bedouin (who did not migrate to Medina) did not inherit from an emigrant, and an emigrant did no inherit from him. It was abrogated by the verse: "But kindred by blood have prior rights against each other."
{ وَأُولُو الأَرْحَامِ بَعْضُهُمْ أَوْلَى بِبَعْضٍ }
