From Sahih Muslim (Hadith 3709):
Fatima bint Qais (Allah be pleased with her) reported:My husband divorced me with three pronouncements. I decided to move (from his house to another place). So I came to Allah's Messenger (ﷺ), and he said: Move to the house of your cousin 'Amr b. Umm Maktum and spend your period of 'Idda there
