I Regret....

First of all not both partners, only women has to do Halala

2ndly there are considerable number of ulemas (yeah sunni ulemas too) who believe (or are of the opinion) that you simply cant do talaq 3 times in one sitting and there is a mandatory "cooling off" period b/w 1st and 2nd talaq and then 2nd and 3rd talaq. Just repeating the word "talaq" 3 times in a second does not constitute 3 legitimate talaqs. Now its the matter of who do you follow.

and sweetdoll, you sure you are not rushing to go back to him just like you rushed to take divorce? and do you even know if he really wants to be with you again?
