Sahih Muslim Book 9, Hadith Number 3534.

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

Ibn al-Qasim narrated on the authority of his father that ‘Urwa b. Zubair (Allah be pleased with him) said to ‘Aisha (Allah be pleased with her): Didn’t you see that such and such daughter of al-Hakam was divorced by her husband with an irrevocable divorce, and she left (the house of her husband)? Thereupon ‘Aisha (Allah be pleased with her) said: It was bad that she did. He (Urwa) said: Have you not heard the words of Fatima? Thereupon she said: There if no good for her in making mention of it.
