18. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from abu Ayyub from abu al-Sabbah who has said the following:

“This is concerning my question before abu ‘Abd Allah , about the case of a man who marries and finds Qarn in her. He (the Imam) said, ‘She cannot become pregnant and her husband cannot go to bed with her, so she is compelled to return to her family and she has no mahr (dower).’ I then asked, ‘What happens if he has gone to bed with her?’ He (the Imam) said, ‘If he knew about it before going to bed with her then went to bed, he has agreed and if he comes to know it after going to bed then he can keep if he so wishes, or return her and she can have what she has received as mahr (dower).”’
