52:23
يَتَنَـٰزَعُونَ فِيهَا كَأْسًا لَّا لَغْوٌ فِيهَا وَلَا تَأْثِيمٌ
yatanāzaʿūna fīhā kasan lā laghwun fīhā walā tathīmun
They pass around a cup which does not lead to any idle talk or sin.
There they shall pass from hand to hand a (wine) cup, free from any Laghw (dirty, false, evil vain talk between them), and free from sin (because it will be lawful for them to drink).
