Currently a girl can marry at age 16, and a boy 18. They wanted to raise the age to 18 for girls, and mete out harsher punishments for those who married underage young girls. That's now not going to happen.
CII's Mohammad Khan Sheerani said:
“Parliament cannot create legislation that is against the teachings of the Holy Quran or Sunnah.”
In fact, they want marriage laws to comply with Shariah, which means that girls as young as nine should be allowed to marry, if "the signs of puberty are visible”. In other words, they want to legalize pedophilia.
Way to go Pakistan.
