Answer
(Fatwa: 267/267/M=1432)
If one does not pronounce the word of talaq verbally and only intends in heart, no talaq shall take place. However, if someone gives talaq to his wife in jest, the talaq takes place. In the same way, if one gives talaq by addressing the wife with the word of sarih (clear-cut) talaq or pointing out to her or attributing towards her, then too talaq takes place. There is no need of intention in sarih words.
