Answered by Shaykh Amjad Rasheed
Is it permissible for a fasting person to kiss their spouse during the day?
If he fears that this will stimulate his desire, such that sperm will exit, then [s. kissing her] is haram.
But if he does not fear this, then it is not haram, though it is better for him not to do it, as has come in the Minhaj with the Tuhfa. (3:410-411)
