وَإِن كُنتُم عَلىٰ سَفَرٍ وَلَم تَجِدوا كاتِبًا فَرِهانٌ مَقبوضَةٌ ۖ فَإِن أَمِنَ بَعضُكُم بَعضًا فَليُؤَدِّ الَّذِي اؤتُمِنَ أَمانَتَهُ وَليَتَّقِ اللَّهَ رَبَّهُ ۗ وَلا تَكتُمُوا الشَّهادَةَ ۚ وَمَن يَكتُمها فَإِنَّهُ آثِمٌ قَلبُهُ ۗ وَاللَّهُ بِما تَعمَلونَ عَليمٌ

If you are traveling and can’t find a scribe, a security deposit should be received. If you trust one another, let the one entrusted fulfill his trust, and let him fear God, his Lord. Don’t conceal the testimony, for whoever conceals it, his heart is sinful. God is fully aware of what you do.
