No Laghw (evil vain talk) will they hear therein, nor any sinful speech. But only the saying of;
"Salaman (peace,)!
Salaman (peace.)!"
meaning they will not hear foul or unnecessary speech in Paradise.
لااَّ تَسْمَعُ فِيهَا لَـغِيَةً
Where they shall neither hear harmful speech nor falsehood. (88;11),
meaning, no foul words are uttered therein.
Allah said,
وَلَا تَأْثِيمًا
(nor any sinful speech), meaning, nor speech that contains foul words,
إِلاَّ قِيلً سَلَمًا سَلَمًا
(But only the saying of;"Salaman (peace!), Salaman (peace!).", they will greet each other with Salam, just as Allah said in another Ayah,
تَحِيَّتُهُمْ فِيهَا سَلَـمٌ
Their greeting therein will be;"Salaman (peace!)." (14;23)
And, as we mentioned, their words will be free from impure and needless speech
