You can read the text of the old (before women protection bill) hudood ordinances here:-

Offence of Zina (Enforcement of Hudood) Ordinance (VII of 1979)
Offence of Qazf (Enforcement of Hadd) Ordinance (VIII of 1979)

The following documents are available on Punjab Police's website:-

Code of Criminal Procedure (Act V of 1898)
Pakistan Penal Code (Act XLV of 1860)
Statement II - Tabular Statement of Offences

Beware! These documents are not fully up-to-date, but nevertheless, are quite helpful for research purposes.

Study these documents and the text of the ordinances. You can also discuss particular things here or in other similar threads.

Still waiting for comments on my article...
