Sahih Muslim | Book 9 | Hadith Number 3514
Narrated by Fatima bint Qais
Fatima bint Qais reported that her husband al-Makhzulmi divorced her and refused to pay her maintenance allowance. So she came to Allah's Messenger (may peace he upon him) and informed him, whereupon he said: There is no maintenance allowance for you, and you better go to the house of Ibn Umm Maktum and live with him for he is a blind man and you can put off your clothes in his house (i.e. you shall not face much difficulty in observing purdah there).
