What is the ruling on a fiancé dancing in front of women, claiming it is out of joy for his friend, and is his statement correct that a man dancing in front of a woman is not forbidden?

Scholars have cited the noble verse: "And do not walk upon the earth exultantly," as evidence for the condemnation of dancing, considering it a form of amusement and folly that diminishes one's dignity. The Hanafis, Malikis, Hanbalis, and Al-Qaffal among the Shafi'is deemed it reprehensible (makrooh).

Dancing becomes unequivocally forbidden if it is accompanied by a prohibited act, such as drinking alcohol or revealing 'awrah (intimate parts). Al-Qurtubi indicated that the dance of the Abyssinians (Habasha) was a leaping with weapons and playing with spears, not dancing in a manner of amusement and folly.

Sheikh Ibn 'Uthaymeen mentioned that dancing is disliked (makrooh), and he was of the opinion that it should be prevented, especially the dancing of women, due to the potential for fitna (temptation/strife) among them.

As for what some common people sometimes do on certain occasions, while adhering to Islamic guidelines, such as ensuring safety from fitna, covering 'awrah, and avoiding anything that incites desires, it is hoped that there is leniency in the matter. This is supported by the hadith where the Prophet (peace be upon him) stood for Aisha while she watched the Abyssinians playing and zafana (a type of dance).

Regarding the suitor entering with his companion upon his wife while she is wearing her jewelry, and him dancing among the women, this is absolutely impermissible. This is because women are often adorned in their finest attire on such occasions, which can lead to fitna between the sexes.
