Imams across Canada and the U.S. have issued a moral ruling condemning honour killings, domestic violence and misogyny as "un-Islamic."

The Islamic Supreme Council of Canada says the fatwa aims to clarify any possible confusion over the teachings of the Qur'an.

The ruling comes after a verdict was delivered in the Shafia murder trial, in which a Montreal couple and their son were convicted of killing four female relatives.

The Crown alleged the three Shafia sisters and their father's first wife in a polygamous marriage were killed in an effort to restore the family's honour.

The trial captured worldwide attention and cast a shadow over Canada's Islamic community, prompting many to speak out against domestic violence.

Syed Soharwardy, a Calgary-based imam who founded the council, says religious leaders are taking a stronger stand in issuing a fatwa, which is "morally binding" for Muslims.
