Musannaf Ibn Abi Shayba 9:1055

'Abd al-Wahhab ibn 'Ata narrated to us, from Sa'id, from Qatadah, from al-Hasan, Sa'id ibn al-Musayyib, and Khilas, who said: "If he marries a virgin upon his wife, he stays with her for three [days/nights], then he divides [his time]. And if he marries a previously married woman, he stays with her for two nights, then he divides [his time]."
