What is the ruling on kissing female mahrams?

The questioner : May Allah forgive you, O Shaykh. What is the ruling on kissing women who are not mahrams, meaning not non-mahram women, but rather like a mother or a sister?

The Shaykh : Kissing one's wife is known to be among the recommended matters, because the Prophet (peace and blessings be upon him) said: And the Messenger (peace and blessings be upon him) used to kiss his wives while fasting. So kissing a woman is among the recommended matters, specifically the wife. As for kissing mahrams, if it is the mother, or an older sister, or the grandmother, or the daughter, then there is no harm in it. Abu Bakr (may Allah be pleased with him) kissed his daughter A'ishah (may Allah be pleased with her) on her cheek. As for other mahrams, meaning those who are not ancestors or descendants, it is better not to kiss them unless they are, as I said, an older sister; in that case, he kisses her on her forehead or on her head. As for kissing a young sister, Satan flows through the son of Adam like blood, so let him avoid this and not kiss her. More emphatic in warning against this is kissing one's mahrams through breastfeeding, because mahrams through breastfeeding are less revered by a person than mahrams through blood relation. Therefore, one must be cautious about kissing one's sister through breastfeeding, especially if she is young and beautiful, because Satan flows through the son of Adam like blood.
In summary, kissing the wife is recommended. Kissing other mahrams, if they are from the ancestors or descendants, there is no harm in it. If they are from others, it is better to be cautious about it. Yes.
