I would like to know if it is Halal to take the hand of my wife in my hand when I go outside in public ? What about kissing her hand, as a gesture of affection to her (even if she wears Niqab and gloves) ? I think in Arab lands, this is not something practiced by the people, and I would like to know if this is due to customs and culture, or if there is a genuine Daleel behind that ?
