"Would you give him his garden (the marriage gift he had given her) back?" she said: "Yes". The Prophet then instructed the man to take back his garden and accept the dissolution of the marriage"
This quote relates to a woman asking for divorce 'without giving any reason'.... she went for arbitration and agreed to the decision thereof to that she would let go the garden she had given her husband earlier . I am not sure about this tradition yet I do not find anything wrong with it because that is 'mutual' and 'by consent'.
