(Furqan) 25 : 72
وَالَّذِينَ لَا يَشْهَدُونَ الزُّورَ وَإِذَا مَرُّوا بِاللَّغْوِ مَرُّوا كِرَامًا
And those who don’t witness to falsehood, and when they pass near play and amusement, they pass by with dignity.
The believer who considers the Lord as the Impartial is conscious that he will be questioned about his hearing, sight, intelligence, and time on the Day of Judgment. So he doesn’t witness and indulges in aimless and heedless activities. See explanation 4: 140; 22: 30; 23: 3 and 25: 63.
