It gets better:
Muslim gang rape victim stabbed in honor-killing ordered by her own mother because she was “unclean”
Muslims commit 91 percent of honor killings worldwide. A manual of Islamic law certified as a reliable guide to Sunni orthodoxy by Al-Azhar University, the most respected authority in Sunni Islam, says that “retaliation is obligatory against anyone who kills a human being purely intentionally and without right.”
However, “not subject to retaliation” is “a father or mother (or their fathers or mothers) for killing their offspring, or offspring’s offspring.” (‘Umdat al-Salik o1.1-2). In other words, someone who kills his child incurs no legal penalty under Islamic law.
In this case, of course, the victim was the murderer’s wife, a victim to the culture of violence and intimidation that such laws help create.
