Do you know of any good Pakistani website or place in Pakistan where one can read more on Islam?

it depends on what you want to know, like if you want to know from a particular sect and read their books, there are many websites of different sects as per their thoughts etc., also there are many websites which have ISLAM in their domain name but operated by Qadianis and Christian Missionaries ant their goal is to misguide people about Islam, well i m from Sunni Barelvi Sect so i suggest some websites like http://www.ahlesunnat.net and http://www.tafseerequran.net

Furthermore if you want to read or download Islamic E-Books i suggest you to visit http://www.4shared.com here you can find books on all subjects in different languages.

Check this is one:- http://www.yanabi.com

about the madrassas, I have no idea as I dun live there but im sure there are some.

I follow this website, MashAllah this is very good website containing extensive knowledge and also answers many queries...!!
