2:282 Believers, when you contract a debt for a fixed period, put it in writing. Let a scribe write it down between you with fairness; no scribe shall refuse to write as Allah has taught him. Therefore, let him write; and let the debtor dictate, fearing Allah his Lord, and do not decrease anything of it. If the debtor is a fool, or weak, or unable to dictate himself, let his guardian dictate for him in fairness. Call to witness two witnesses of your men, if the two are not men, then a man and two women from the witnesses whom you approve; so that if one of the two errs, one of them will remind the other. Whenever witnesses are called upon they must not refuse, and do not be weary to write it down, be it small or large, together with its term. This is more just with Allah; it ensures accuracy in testifying and is the least of doubt. Unless it is present merchandise that you circulate between you; then no guilt shall be on you if you do not write it down and take witnesses when you are selling, and let no harm be done to either scribe or witness. If you do, that is a transgression in you. Fear Allah. Allah teaches you, and Allah has knowledge of everything.

2.282 يَا أَيُّهَا الَّذِينَ آمَنُواْ إِذَا تَدَايَنتُم بِدَيْنٍ إِلَى أَجَلٍ مُّسَمًّى فَاكْتُبُوهُ وَلْيَكْتُب بَّيْنَكُمْ كَاتِبٌ بِالْعَدْلِ وَلاَ يَأْبَ كَاتِبٌ أَنْ يَكْتُبَ كَمَا عَلَّمَهُ اللّهُ فَلْيَكْتُبْ وَلْيُمْلِلِ الَّذِي عَلَيْهِ الْحَقُّ وَلْيَتَّقِ اللّهَ رَبَّهُ وَلاَ يَبْخَسْ مِنْهُ شَيْئًا فَإن كَانَ الَّذِي عَلَيْهِ الْحَقُّ سَفِيهًا أَوْ ضَعِيفًا أَوْ لاَ يَسْتَطِيعُ أَن يُمِلَّ هُوَ فَلْيُمْلِلْ وَلِيُّهُ بِالْعَدْلِ وَاسْتَشْهِدُواْ شَهِيدَيْنِ من رِّجَالِكُمْ فَإِن لَّمْ يَكُونَا رَجُلَيْنِ فَرَجُلٌ وَامْرَأَتَانِ مِمَّن تَرْضَوْنَ مِنَ الشُّهَدَاء أَن تَضِلَّ إْحْدَاهُمَا فَتُذَكِّرَ إِحْدَاهُمَا الأُخْرَى وَلاَ يَأْبَ الشُّهَدَاء إِذَا مَا دُعُواْ وَلاَ تَسْأَمُوْاْ أَن تَكْتُبُوْهُ صَغِيرًا أَو كَبِيرًا إِلَى أَجَلِهِ ذَلِكُمْ أَقْسَطُ عِندَ اللّهِ وَأَقْومُ لِلشَّهَادَةِ وَأَدْنَى أَلاَّ تَرْتَابُواْ إِلاَّ أَن تَكُونَ تِجَارَةً حَاضِرَةً تُدِيرُونَهَا بَيْنَكُمْ فَلَيْسَ عَلَيْكُمْ جُنَاحٌ أَلاَّ تَكْتُبُوهَا وَأَشْهِدُوْاْ إِذَا تَبَايَعْتُمْ وَلاَ يُضَآرَّ كَاتِبٌ وَلاَ شَهِيدٌ وَإِن تَفْعَلُواْ فَإِنَّهُ فُسُوقٌ بِكُمْ وَاتَّقُواْ اللّهَ وَيُعَلِّمُكُمُ اللّهُ وَاللّهُ بِكُلِّ شَيْءٍ عَلِيمٌ
