I would like to know that in an argument between husband and wife, if a woman says to her husband "leave me", then "divorce me" and the husband replies back "are you sure?" and he gives her 3 talaqs at once. Is that considered as full 3 talaqs or qulla (khul') talaq.
We both are Sunnis.
And if it is not, please can you provide proof in Quran and hadiths.
Many are saying different things and I am very confused.
