What is the authenticity of the story of Abdullah ibn Jahsh with Al-Sahbaa Al-Hudhaliyyah mentioned in the book "Al-Aghani," and is one sinful for relating it, and is there sin upon whoever commented on it, laughing at the description "the intensity of her constriction" within it?

What was mentioned in the story is not an act of disbelief (kufr). Abdullah ibn Jahsh, who was mentioned in the story, is not a Companion of the Prophet. Rather, he was a poet who died during the time of Abd al-Malik, whereas there are two Companions named Abdullah ibn Jahsh: the first was martyred on the Day of Uhud, and the second is Ibn Umm Maktum, concerning whom the verse was revealed: "Not equal are those of the believers who sit [at home], other than those who have a [disabling] injury, and those who strive in the cause of Allah with their wealth and their lives." This story is from the narrations of historians and litterateurs, and no ruling can be derived from it. It should be noted that many scholars have accused Abu al-Faraj al-Isfahani (author of Al-Aghani). It is more befitting for a Muslim to occupy himself with the sciences of the Qur'an and Sunnah (definition). There is no harm in seeking recreation through literature and narrations, provided that the best of them are chosen.
