Most, though not all, members of the family that were in politics were known by their title, Qazi, which is the name given to certain Judges under Islamic Law, instead of their last name "Abbasi".
The Qazi/Abbasi family originally hailed from Sehwan in Sindh and migrated to Hyderabad when Qazi Abdul Qayyum settled there.
Qazi Abdul Qayyum's brother, Hakeem Fatheh Muhammad Sehwani, who chose to use the title Hakeem, settled in Karachi after leaving Sehwan, where he established another branch of the family.
In journalistic circles, the family publishes several Sindhi language newspapers including the Daily Ibrat.
In addition, the family served the journalistic community through its involvement in the All Pakistan Newspapers Society.
