witnesses told to be truthful

۞ وَإِن كُنتُمْ عَلَىٰ سَفَرٍ وَلَمْ تَجِدُوا۟ كَاتِبًا فَرِهَـٰنٌ مَّقْبُوضَةٌ ۖ فَإِنْ أَمِنَ بَعْضُكُم بَعْضًا فَلْيُؤَدِّ ٱلَّذِى ٱؤْتُمِنَ أَمَـٰنَتَهُۥ وَلْيَتَّقِ ٱللَّهَ رَبَّهُۥ ۗ وَلَا تَكْتُمُوا۟ ٱلشَّهَـٰدَةَ ۚ وَمَن يَكْتُمْهَا فَإِنَّهُۥٓ ءَاثِمٌ قَلْبُهُۥ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ

If you are on a journey, and cannot find a scribe, something should be handed over as security, but if you decide to trust one another, then let the one who is trusted fulfil his trust; let him be mindful of God, his Lord. Do not conceal evidence: anyone who does so has a sinful heart, and God is fully aware of everything you do.

You who believe, be steadfast in your devotion to God and bear witness impartially: do not let hatred of others lead you away from justice, but adhere to justice, for that is closer to awareness of God. Be mindful of God: God is well aware of all that you do.

وَٱلَّذِينَ لَا يَشْهَدُونَ ٱلزُّورَ وَإِذَا مَرُّوا۟ بِٱللَّغْوِ مَرُّوا۟ كِرَامًا

[The servants of the Lord of Mercy are] those who do not give false testimony, and who, when they see some frivolity, pass by with dignity;
