And Allah said in Surah An-Nisa «ولن تستطيعوا أن تعدلوا بين النساء»: "But if you fear that you shall not be able to deal justly (with them), then (marry) only one." Until the end of the verse «واسعا حكيما».
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.
