The Doomed are preoccupied with Idle Talk and They turn away from the Ayat of Allah When Allah mentions the blessed -- who are those who are guided by the Book of Allah and benefit from hearing it, as He says:
Allah has sent down the Best Statement, a Book, its parts resembling each other (and) oft-repeated. The skins of those who fear their Lord shiver from it. Then their skin and their heart soften to the remembrance of Allah (39:23). He connect that with mention of the doomed, those who turn away from the Qur'an and do not benefit from hearing the Words of Allah. Instead, they turn to listening to flutes and singing accompanied by musical instruments. As Ibn Mas`ud commented about the Ayah:
And of mankind is he who purchases Lahu Al-Hadith to mislead (men) from the path of Allah, he said, "This -- by Allah -- refers to singing.''
And of mankind is he who purchases Lahw Al-Hadith to mislead (men) from the path of Allah without knowledge, Qatadah said: "By Allah, he may not spend money on it, but his purchasing it means he likes it, and the more misguided he is, the more he likes it and the more he prefers falsehood to the truth and harmful things over beneficial things.'' It was said that what is meant by the words
purchases idle talks is buying singing servant girls. Ibn Jarir said that it means all speech that hinders people from seeing the signs of Allah and following His path. His saying:
to mislead (men) from the path of Allah means, he does this to oppose Islam and its followers.
and takes it by way of mockery Mujahid said, "This means mocking the path of Allah and making fun of it.''
For such there will be a humiliating torment Just as they showed no respect to the signs and path of Allah, so they will be shown no respect on the Day of Resurrection, and they will be subjected to a painful, ongoing torment.
