Triple talaq divorce has no mention in Sharia law or the Koran, even though the practice has existed for decades. It is banned in Pakistan, Bangladesh and Saudi Arabia.The custom has continued in India, though. There is no uniform set of laws on marriage and divorce that apply to every citizen.
In recent years, there have been cases in which Muslim men in India have divorced their wives by issuing the so-called triple talaq by letter, telephone and, increasingly, by text message, WhatsApp and Skype. A number of these cases made their way to the courts, as women contested the custom.
