Remember in The Wizard of Oz when Dorothy only had to click her gaudy red shoes and say "There's no place like home" three times to get back to Kansas? Well, apparently it's the same in Islam with divorce. Say "Talaq" (divorce) three times in your sleep and poof --you and your wife are history (whether you want to be or not)...
"Sohela Ansari told friends that her husband Aftab had uttered the word "talaq," or divorce, three times in his sleep, according to the report published in newspapers on Monday.
When local Islamic leaders got to hear, they said Aftab's words constituted a divorce under an Islamic procedure known as "triple talaq." The couple, married for 11 years with three children, were told they had to split.
The religious leaders ruled that if the couple wanted to remarry they would have to wait at least 100 days. Sohela would also have to spend a night with another man and be divorced by him in turn." (source)
