A woman not covering up in the presence of her husband's father by breastfeeding

A: It is permissible for your wife to unveil her face in front of your father by breastfeeding, since he is the one who made your mother by breastfeeding pregnant and enabled her to breast-feed you. Thus, your wife falls under the category of daughters-in-law who are considered Mahrams (unmarriageable relatives) for him. The Prophet (peace be upon him) said: "Breastfeeding relationships are equal to blood relationships in rendering (marriage) unlawful." Q 3: A woman breast-fed my wife more than five times. Is it permissible for that woman to unveil her face in front of me? A: It is permissible for your wife's mother by breastfeeding to unveil her face in front of you, as she falls under the category of mothers-in-law who are considered Mahrams for you.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
