Salam Alaikum
Hazrat Abbas (A) had two daughters and five sons:
1-- Ubaidullah
2-- Fazl
3-- Hasan
4-- Qasim
5-- Mohammad
Ibn Shahrashub, a famous historian, reports that Mohammad was martyred with his father in Karbala.
The mother of Ubaidullah and Fazl was Lubaba bint Ubaidullah ibn Abbas ibn Abdil-Muttalib, who some say was present in Karbala.
Historians say that the progeny of Hazrat Abbas came from his sons Ubaidullah and Hasan, and many in Pakistan claim that they are also decendents of Fazl ibn Abbas ibn Ali.
