In the
ṭalāq divorce, the husband pronounces the phrase "I divorce you" (in Arabic,
talaq) to his wife. A man may divorce his wife three times, taking her back after the first two (reconciling). After the third
talaq they can't get back together until she marries someone else. Some do a "triple ṭalāq", in which the man says in one sitting "I divorce you" three times (or "I divorce you, three times", "you're triple divorced"). Many Islamic scholars believe there is a waiting period involved between the three talaqs, pointing to Quran 65:1 and various
hadiths. However the practice of "triple ṭalāq" at one sitting has been "legally recognized historically and has been particularly practiced in Saudi Arabia."
