صحيح مسلم

Ibn Abu Bakr b. Abd al-Rahman reported that when Allah's Messenger (ﷺ) married Umm Salama and she stayed with him (during the night), and it was dawn, he (the Holy Prophet) said to her: There is no lack of estimation for you on the part of your husband. So if you desire I can spend a week with you, and if you like I may spend three (nights). and then I will visit you in turn. She said: Spend three (nights).
