What did the Prophet Muhammad (saw) say regarding how long a man should stay with his second wife, if he already has one wife, whether a virgin or a matron?
 Narrated Anas:                     The tradition, (of the Prophet) is that if someone marries a virgin and he has already a matron wife (with him), then he should stay with the virgin for seven days; and if someone marries a matron (and he has already a virgin wife with him) then he should stay with her for three days.
