Sahih Muslim Book 9, Hadith Number 3521.

Chapter: There is no maintenance allowance for one who has been given irrevocable divorce.

Sha’bi reported: We visited Fatima hint Qais and she served us fresh dates and a drink of barley flour, and I asked where a woman who has been divorced by three pronouncements should, spend the period of her ‘Idda. She said: My husband divorced me with three pronouncements, and Allah’s Apostle (may peace be upon him) permitted me to spend my ‘Idda period in my family (with my parents).
