Aside from "a few rare and isolated" instances from the pre-modern era and several recent cases, there is no historical record of stoning for zina being legally carried out. Zina became a more pressing issue in modern times, as Islamist movements and governments employed polemics against public immorality. After sharia-based criminal laws were widely replaced by European-inspired statutes in the modern era, in recent decades several countries passed legal reforms that incorporated elements of hudud laws into their legal codes. Iran witnessed several highly publicized stonings for zina in the aftermath of the Islamic revolution. In Nigeria local courts have passed several stoning sentences, all of which were overturned on appeal or left unenforced. While the harsher punishments of the Hudood Ordinances have never been applied in Pakistan, in 2005 Human Rights Watch reported that over 200,000 zina cases against women were underway at various levels in Pakistan's legal system.
