Is it permissible for a woman to praise a man in front of her husband, and vice-versa?

The basic principle is the permissibility of praising people and commending them for the good within them, based on the Almighty's saying: "And speak to people good words." This is done through kind words, and there is no difference between a man and a woman in praise, unless it leads to a forbidden consequence, such as the jealousy of one of the spouses. It is also stipulated that the praise should not include a description of a man's beauty to a woman or vice-versa, according to the Prophet's (PBUH) saying: "A woman should not touch another woman and then describe her to her husband as if he were looking at her."
