Just remember Malik Riaz announced two billion dollars for flood victims , two year ago , According to him at CNN , 2/3 of his fortune (Never given) and much more black money so according to that , He is the richest one in Pakistan (And also most powerful person)
Even he himself doesn't know the standing of his business.. which is mostly running on cash flow.. with probably a very deep hole inside. CNN announcement was merely a publicity stunt to fool people as the basic requirement of his business is to get more and more money from people's pocket. In any case he probably does not rank amongst even the first 100.. He is certainly not a member of the first 10 club..
We have one Pakistani businessman in Bahrain and its own by Mr. Hamid Nishat. I think he's son/relative of Mian Mansha Nishat b'coz his nature of business is about 'textile'.
No connection.. Mian Mansha is a Chinioti and has three sons.. all of them live in Pakistan..
I doubt it.. I know very well Mian Idrees's whole business profile.. it's not even a fraction of Mansha and Sir Pervaiz.. I would not put him in the first 10 club. The only eligible candidate from Faisalabad is probably Naeem Mukhtar of Ibrahim-Allied Bank ..
Maybe i have wrong information about Mian Jee, my close uncle use to work with him in early 70s when he setup his unit in then East Pakistan.
let me try to make a list (according to my flawed knowledge)
1) Mian Mansha
2) Sir Anwar Pervaiz
3) Hussain Dawood
4) House of Habib
5) Jahangir Sidddqui
6) Mohammad Ali Tabba
7) Mian Abdullah
8) Naeem Mukhtar
9) Arif Habib
10) Syed Babar Ali

I am sure this list has a lot of flaws..
Your list is according to known sources .
Generals , Politicians , Bureaucrats , Mafia people , Chanda Khors , Bhatta khors and Smugglers can not be counted ,
But they are more rich .
