Is it permissible for the wife to object to her husband spending one night of the weekend with his friends, talking, playing cards, and smoking shisha, on the grounds that it is his right and that the rest of the week is hers, knowing that they both observe their prayers? And does the ruling differ if the night out is for the obedience of Allah?

There must be understanding and affection between spouses. There is no objection to a man meeting with his friends for recreation and permissible conversation, provided that there is nothing objectionable in it. Smoking shisha is forbidden, and playing cards is disliked unless it involves gambling, in which case it is forbidden. Staying up late after Isha prayer is disliked because it leads to neglecting prayers, unless it is for an act of obedience such as prayer, reciting the Qur'an, or seeking knowledge, in which case it is beloved and desirable, provided it does not lead to neglecting obligatory acts of worship. Habitually staying up late after Isha is disliked, and if it is associated with something forbidden, then it is forbidden, and if it is for an act of obedience, then it is permissible or desirable. There is no harm in a husband occasionally staying up late with his friends, provided he does not neglect his wife's rights and there is nothing forbidden in the late night gathering. It is advisable to be gentle and understanding when offering advice.
