Is playing billiards in designated places, provided that these places are free of music and unveiled women, and playing during leisure time and not prayer times, considered reprehensible or a waste of time, in two cases: the presence of shisha and smokers, or the place being completely free of that?

If a place contains unlawful acts, such as smoking and the intermingling of men and women, it is an objectionable place, and it is not permissible to sit in it except for one who intends to change theable act. If the place is free of unlawful acts, then it is permissible to sit and play in it, provided the rules of the game are adhered to.
