I would like to ask that is it compulsory to say Talaaq work to divorce a woman? If said 'I will leave you/I divrorce you' is Talaaq valid? As I was very angry with my wife and I told her I leave you know but did not say any word like Talaaq, is my marriage invalid? As we are still leaving together and still we have same relations like before. Please advice.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

Your saying "I leave you" is not a clear word of divorce rather it is an illusive expression. The ruling of such a word depends on the intention of the person. If he utters it with the intention of divorce then it is considered divorce; otherwise, divorce is not effective.
