One who says to his wife: you are divorced

Sa'd bin Ibrahim said: A man said to his wife, "You are divorced." He asked Salim (may Allah have mercy on him) and al-Qasim (may Allah have mercy on him) about it, and they said: Our view is that he should be made to swear that he did not intend an irrevocable (battah) divorce.

Sa'id bin al-Musayyib (may Allah have mercy on him) said: If a man says to his wife, "You are divorced," without mentioning the number, his intention will be taken into account, whether he gave one, two or three.
