Is it acceptable in Islam for a man to hug and kiss his adult sister ?
Can an adult brother hug or kiss his adult sister? Allah (SWT) establishes a beautiful and sacred bond between siblings born of the same parents. This Mahram relationship prohibits marriage and fosters deep respect and love between brother and sister. Within this relationship, there is absolutely no harm in a brother showing affection towards his sister through occasional touches, cuddles, hugs, or even a kiss on the cheek. These gestures, motivated by pure brotherly love, strengthen the bond between siblings. Hugging and kissing mahram women with brotherly or fatherly affection, is in fact sunnah and is recommended thing to do. Aishah said, “The Prophet once kissed Fatimah on the neck. I told him, ‘O Prophet, you treat Fatimah in a way that you do not treat others.’ The Prophet said, ‘O ‘Aishah, whenever I take interest in the Paradise, I kiss her on the neck.’[ Source ] A sister hugging her brother
