They will not hear therein ill speech or commission of sin - meaning

*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.
