Saying, “You are” in anger?
In the name of Allah, the most Beneficent, the most Merciful.
It is mentioned in Durrul Mukhtar:
“The main part (rukn) of divorce is the specific statement.” (Raddul Muhtar p.426 v.4)
For divorce to occur it is necessary that the words of divorce are executed either clearly which will result in the divorce occurring straightaway or ambiguously which will result in the divorce occurring if there was intention or through “Dalalat Haal” (prevalent circumstances).
With regards to your question if the husband said, “you are” whether it was said in anger or not it will no break the marriage.
Only Allah Knows Best
