Muwatta Malik 1106
موطأ مالك#1106SahihYahya related to me from Malik from Humayd at-Tawil that Anas ibn Malik said, "A virgin has seven nights, and a woman who has been previously married has three nights." Malik affirmed, "That is what is done among us." Malik added, "If the man has another wife, he divides his time equally between them after the wedding nights. He does not count the wedding nights against the one he has just married
