Supreme Court is considering petitions that challenge Muslim laws governing marriage on the grounds that they discriminate against women, a charged issue that risks angering the country’s orthodox Muslims. Among the petitioners calling for change is Shayara Bano, a Muslim woman whose husband, after 13 years of marriage, divorced her by triple talaq, a practice that allows Muslim men in India to leave their wives unilaterally and often instantaneously by saying “talaq,” meaning divorce, three times.
