Is a man prohibited from marrying the daughter of a woman after he has proposed to her mother?

The daughter of the wife becomes forbidden [in marriage] if the marriage contract with the mother is concluded and consummation takes place. However, a mere engagement or a marriage contract without consummation does not make the daughter forbidden, based on the Almighty's saying: "{And your stepdaughters who are under your guardianship, born of your wives with whom you have consummated marriage. But if you have not consummated marriage with them, then there is no blame upon you [to marry their daughters]}."
