Praise be to Allah the Lord of the Worlds.
We have searched the books of Hadith and found nothing about this story.
As for the religious ruling on the person who tells his wife: "You are divorced until a certain point in time," the divorce takes place immediately.
Ashirbini says: "If he said to her: "You are divorced until a certain point in time then divorce takes place immediately, whether theperiod was short or long. Allah The Almighty Says (What means): "when ye reach eventide and when ye rise in the morning." {Moghni Al-Mohtajj, vol.3/pp.332}.
Note: Article (87), Paragraph (B) of the Jordanian Personal Status Law states: "Divorce tied to a certain point in the future isn`t effective." And Allah The Almighty Knows Best.
