Translation of the verse 25 from Surah Al-Waqi‘ah : Number of verses 96 - - page 535 - Part 27.
No Laghw (dirty, false, evil vain talk) will they hear therein, nor any sinful speech (like backbiting, etc.).
They will not hear therein ill speech or commission of sin -
(56:25) There they shall hear no idle talk nor any sinful speech. *13
*13) This is one of the major blessings of Paradise, which has been mentioned at several places in the Qur'an, viz. that in Paradise human ears will remain secure against idle and frivolous talk, lying, backbiting slander, invective, boasting and bragging, taunts and mockery, satire and sarcasm. It will not be a society of foul-mouthed, indecent people who will throw mud at each other, but a society of noble and civilized people free of such frivolities. A person who has been blessed with some deceney of manner and sense by Allah can very well feel what an agony it is in worldly life a hope of deliverance from which has been given to man in Paradise.
