Are you related with the family of Shaikh Baha-ud-din Zakarriyah Multani Rahimahumullaah ? If yes , then his family is also Hashmi Al Asadi descended from Asad Ibn Hashim ,the maternal grandfather of Hadhrat Ali Ibn Abi Talib Radhi Allaahu Anhu !
Very wrongly people have written then Habbari Asadi Quraishi or Simply Quraishi Asadi only ?
He was a Asadi Hashimi and ( as you know all the Hashimis are automatically Quraishi because everyone who is descended from the Quraish family of Makkah is Quraishi, even a Sayyid is also basically a Quraishi and then further he is a Sayyid ?
Their Shajra must be at the shrine of Shaikh Multani at Multan? You need to contact the care-taker of the Dargah ?
If not, then you should contact brother Mohammad Al Hashimi who had written a book on Hashimis !
In any case please do stay in touch as I am also updating my Shajrah and we may get benefitted from each others knowledge, my e-mail ID is Khalidkoraivi@yahoo.com
