Surah Al-Baqara, Verse 283
۞ وَإِن كُنتُمْ عَلَىٰ سَفَرٍۢ وَلَمْ تَجِدُوا۟ كَاتِبًۭا فَرِهَٰنٌۭ مَّقْبُوضَةٌۭ ۖ فَإِنْ أَمِنَ بَعْضُكُم بَعْضًۭا فَلْيُؤَدِّ ٱلَّذِى ٱؤْتُمِنَ أَمَٰنَتَهُۥ وَلْيَتَّقِ ٱللَّهَ رَبَّهُۥ ۗ وَلَا تَكْتُمُوا۟ ٱلشَّهَٰدَةَ ۚ وَمَن يَكْتُمْهَا فَإِنَّهُۥٓ ءَاثِمٌۭ قَلْبُهُۥ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌۭ
Translation — Sahih International
And if you are on a journey and cannot find a scribe, then a security deposit [should be] taken. And if one of you entrusts another, then let him who is entrusted discharge his trust [faithfully] and let him fear Allah, his Lord. And do not conceal testimony, for whoever conceals it - his heart is indeed sinful, and Allah is Knowing of what you do.
