The practice of so-called "honour killing" is in reality an act of murder. It is usually carried out against a female family member who is seen by relatives as dishonoring their family through real or perceived acts of indiscretion, such as premarital sexual relations or unapproved dating. In many cases of "honour killing", the accused woman is innocent, and is killed purely based on suspicion. In other cases, the issue of "honour" is used as a cover to justify a murder that was really committed for other purposes. No matter what the reason is, "honour killing" is a despicable crime.
Quran 4:15 states that a "lewd" woman is to be put under house arrest till death, if she's caught committing a "lewd" act by 4 witnesses.
This has been explained in tafsirs & in hadiths as being abrogated by latter verses which say that an unmarried woman commiting lewdness ie fornication has to be given 100 lashes, & a married adulteress stoned to death. Exactly like many other supposedly abrogated verses, this verse too still remains in the Quran.
These are verses from the Quran:
YUSUFALI: If any of your women are guilty of lewdness, Take the evidence of four (Reliable) witnesses from amongst you against them; and if they testify, confine them to houses until death do claim them, or Allah ordain for them some (other) way.
PICKTHAL: As for those of your women who are guilty of lewdness, call to witness four of you against them. And if they testify (to the truth of the allegation) then confine them to the houses until death take them or (until) Allah appoint for them a way (through new legislation).
SHAKIR: And as for those who are guilty of an indecency from among your women, call to witnesses against them four (witnesses) from among you; then if they bear witness confine them to the houses until death takes them away or Allah opens some way for them.
Obviously, these verses have some flexibility of interpretation, ie "Allah" opening some way for them," can well be interpreted by the women's judges & families as they taking over from Allah & letting the woman go, & this punishment can well be substituted by a light lashing, which would be more preferable for the woman.
However, they can also be interpreted as locking women up, often for decades, simply for "lewdness". Lewdness btw isn't the same as adultery or fornication, its left to the families & societies to decide what constitutes lewdness & indecency, & free intermingling of sexes, having male friends etc is considered lewdness in plenty of Islamic societies with Prophet Mo himself saying in hadiths, that when a man & woman are alone together, the third person present is the Devil.
Canada's biggest honour killing trial has begun What is most interesting about this case is right from the get go our liberal media did not want to label this multiple homicide as an honour killing despite the fact that it was so blatantly obvious that the three sisters and the first wife were murdered for honour.
