Does divorce occur with the words, "You are divorced, divorced, divorced, irrevocably," when there is no certainty of the intention to divorce upon discovering the contingent act three years later, and is it considered one divorce or three?

If this phrase was written but not uttered, its ruling is that of a kinayah (allusion), and divorce does not occur by it unless you intended to effect it thereby. If you are not certain about the intention to effect divorce, the preponderant view with us is that divorce does not occur, because doubt about its occurrence prevents its binding nature. This includes mere supposition and delusion.
