Sahih Bukhari Volume 007, Book 064, Hadith Number 280.
Narrated By Jabir bin 'Abdullah : My father died and left seven or nine girls and I married a matron. Allah's Apostle said to me, "O Jabir! Have you married?" I said, "Yes." He said, "A virgin or a matron?" I replied, "A matron." he said, "Why not a virgin, so that you might play with her and she with you, and you might amuse her and she amuse you." I said, " 'Abdullah (my father) died and left girls, and I dislike to marry a girl like them, so I married a lady (matron) so that she may look after them." On that he said, "May Allah bless you," or "That is good."
