Sunan Ibn Majah, Chapter: The Chapters on Divorce

"A man from among the Ansar married a woman from Balijlan. He entered upon her and spent the night with her, then in the morning he said: 'I did not find her to be a virgin.' Her case was taken to the Prophet (saw), and he called the girl and asked her. She said: 'No, I was a virgin.' So he told them to go through the procedure of Li'an, and gave her the bridal-money.” (Daif)
