Lineage of Nabi (Sallallahu Alaihi Wasallam)
Q: Why are the descendants of only Hazrat Hasan and Hazrat Husain (Radhiyallahu Anhuma) considered to be the extended bloodline of Prophet Muhammad (Sallallahu Alaihi Wasallam) considering Hazrat Fatima had other children too. Adding further, Hazrat Umama also had a child. Is it an exceptional case?
