To say how can you give three talaqs to your wife
With regards to your question the statement ”how can you give three talaq” to a wife and the marriage is over” is a “khabar” i.e. something, which has happened in the past, and for talaq to occur, the husband would need to say an “inshaa” sentence i.e. to make something happen.
Therefore, in the aforementioned scenario three talaqs will not occur. Your wife is still lawful and halal for you. (Raddul Muhtar p.69 v.4)
