(35) باب فِي الْمَقَامِ عِنْدَ الْبِكْرِ
Narrated Anas b. Malik :
When a man who has a wife married a virgin he should stay with her seven nights ; if he marries to a woman who has been previously married he should stay with her three nights. (The narrator said:) If I say that he (Anas) narrated this tradition from the Prophet (ﷺ) I shall be true. But he said: The Sunnah is so-and-so.
