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, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
If the husband says to his wife ‘get out of here’, this does not make divorce take place unless he intends to initiate a divorce. Kindly, refer to the Fataawa 90531 and 98703 about the metaphors of divorce.
As for the statement of that husband to his wife 'I take you back', believing that divorce had taken place, this does not entail the occurrence of divorce and it has no effect at all.
Allaah Knows best.
