The Ruling on a Non-Mahram Examining the Wives of Paternal and Maternal Uncles

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is it permissible for me to examine the wives of my paternal and maternal uncles, knowing that I have reached puberty?

Answer:
It is not permissible to examine the wives of your maternal uncles, or the wives of your paternal uncles, or the wives of your brothers. This is not permissible because you are a non-mahram to them, unless there is a bond of breastfeeding between you. If there is a bond of breastfeeding between you, breastfeeding prohibits what birth prohibits, as the Prophet (peace and blessings be upon him) said. So if it is merely that she is the wife of your brother, or your paternal uncle, or your maternal uncle, and there is no breastfeeding between you, then you are non-mahrams to them. They are required to observe hijab from you, and it is not permissible for you to be alone with any one of them.
