2:282
يَٰٓ أَيُّهَا ٱلَّذِينَ ءَامَنُ وٓا۟ إِذَا تَدَايَن تُم بِ دَيْنٍ إِلَىٰٓ أَجَلٍ مُّسَمًّى فَ ٱكْتُبُ و هُ وَ لْ يَكْتُب بَّيْنَ كُمْ كَاتِبٌۢ بِ ٱلْ عَدْلِ وَ لَا يَأْبَ كَاتِبٌ أَن يَكْتُبَ كَ مَا عَلَّمَ هُ ٱللَّهُ فَ لْ يَكْتُبْ وَ لْ يُمْلِلِ ٱلَّذِى عَلَيْ هِ ٱلْ حَقُّ وَ لْ يَتَّقِ ٱللَّهَ رَبَّ هُۥ وَ لَا يَبْخَسْ مِنْ هُ شَيْـًٔا فَ إِن كَانَ ٱلَّذِى عَلَيْ هِ ٱلْ حَقُّ سَفِيهًا أَوْ ضَعِيفًا أَوْ لَا يَسْتَطِيعُ أَن يُمِلَّ هُوَ فَ لْ يُمْلِلْ وَلِيُّ هُۥ بِ ٱلْ عَدْلِ وَ ٱسْتَشْهِدُ وا۟ شَهِيدَيْنِ مِن رِّجَالِ كُمْ فَ إِن لَّمْ يَكُونَ ا رَجُلَيْنِ فَ رَجُلٌ وَ ٱمْرَأَتَانِ مِ مَّن تَرْضَ وْنَ مِنَ ٱل شُّهَدَآءِ أَن تَضِلَّ إِحْدَىٰ هُمَا فَ تُذَكِّرَ إِحْدَىٰ هُمَا ٱلْ أُخْرَىٰ وَ لَا يَأْبَ ٱل شُّهَدَآءُ إِذَا مَا دُعُ وا۟ وَ لَا تَسْـَٔمُ وٓا۟ أَن تَكْتُبُ و هُ صَغِيرًا أَوْ كَبِيرًا إِلَىٰٓ أَجَلِ هِۦ ذَٰلِكُمْ أَقْسَطُ عِندَ ٱللَّهِ وَ أَقْوَمُ لِ ل شَّهَٰدَةِ وَ أَدْنَىٰٓ أَ لَّا تَرْتَابُ وٓا۟ إِلَّآ أَن تَكُونَ تِجَٰرَةً حَاضِرَةً تُدِيرُ ونَ هَا بَيْنَ كُمْ فَ لَيْسَ عَلَيْ كُمْ جُنَاحٌ أَ لَّا تَكْتُبُ و هَا وَ أَشْهِدُ وٓا۟ إِذَا تَبَايَعْ تُمْ وَ لَا يُضَآرَّ كَاتِبٌ وَ لَا شَهِيدٌ وَ إِن تَفْعَلُ وا۟ فَ إِنَّ هُۥ فُسُوقٌۢ بِ كُمْ وَ ٱتَّقُ وا۟ ٱللَّهَ وَ يُعَلِّمُ كُمُ ٱللَّهُ وَ ٱللَّهُ بِ كُلِّ شَىْءٍ عَلِيمٌ
O you who have believed, when you contract a debt for a specified term, write it down. And let a scribe write [it] between you in justice. Let no scribe refuse to write as Allah has taught him. So let him write and let the one who has the obligation dictate. And let him fear Allah, his Lord, and not leave anything out of it. But if the one who has the obligation is of limited understanding or weak or unable to dictate himself, then let his guardian dictate in justice. And bring to witness two witnesses from among your men. And if there are not two men [available], then a man and two women from those whom you accept as witnesses - so that if one of the women errs, then the other can remind her. And let not the witnesses refuse when they are called upon. And do not be [too] weary to write it, whether it is small or large, for its [specified] term. That is more just in the sight of Allah and stronger as evidence and more likely to prevent doubt between you, except when it is an immediate transaction which you conduct among yourselves. For [then] there is no blame upon you if you do not write it. And take witnesses when you conclude a contract. Let no scribe be harmed or any witness. For if you do so, indeed, it is [grave] disobedience in you. And fear Allah. And Allah teaches you. And Allah is Knowing of all things.
41:38
فَ إِنِ ٱسْتَكْبَرُ وا۟ فَ ٱلَّذِينَ عِندَ رَبِّ كَ يُسَبِّحُ ونَ لَ هُۥ بِ ٱلَّ يْلِ وَ ٱل نَّهَارِ وَ هُمْ لَا يَسْـَٔمُ ونَ
But if they are arrogant - then those who are near your Lord exalt Him by night and by day, and they do not become weary.
41:49
لَّا يَسْـَٔمُ ٱلْ إِنسَٰنُ مِن دُعَآءِ ٱلْ خَيْرِ وَ إِن مَّسَّ هُ ٱل شَّرُّ فَ يَـُٔوسٌ قَنُوطٌ
Man is not weary of supplication for good [things], but if evil touches him, he is hopeless and despairing.
