11:54
إِن نَّقُولُ إِلَّا ٱعْتَرَىٰ كَ بَعْضُ ءَالِهَتِ نَا بِ سُوٓءٍ قَالَ إِنِّ ىٓ أُشْهِدُ ٱللَّهَ وَ ٱشْهَدُ وٓا۟ أَنِّ ى بَرِىٓءٌ مِّ مَّا تُشْرِكُ ونَ
We only say that some of our gods have possessed you with evil." He said, "Indeed, I call Allah to witness, and witness [yourselves] that I am free from whatever you associate with Allah
18:51
مَّآ أَشْهَد تُّ هُمْ خَلْقَ ٱل سَّمَٰوَٰتِ وَ ٱلْ أَرْضِ وَ لَا خَلْقَ أَنفُسِ هِمْ وَ مَا كُن تُ مُتَّخِذَ ٱلْ مُضِلِّينَ عَضُدًا
I did not make them witness to the creation of the heavens and the earth or to the creation of themselves, and I would not have taken the misguiders as assistants.
2:204
وَ مِنَ ٱل نَّاسِ مَن يُعْجِبُ كَ قَوْلُ هُۥ فِى ٱلْ حَيَوٰةِ ٱل دُّنْيَا وَ يُشْهِدُ ٱللَّهَ عَلَىٰ مَا فِى قَلْبِ هِۦ وَ هُوَ أَلَدُّ ٱلْ خِصَامِ
And of the people is he whose speech pleases you in worldly life, and he calls Allah to witness as to what is in his heart, yet he is the fiercest of opponents.
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.
4:6
وَ ٱبْتَلُ وا۟ ٱلْ يَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُ وا۟ ٱل نِّكَاحَ فَ إِنْ ءَانَسْ تُم مِّنْ هُمْ رُشْدًا فَ ٱدْفَعُ وٓا۟ إِلَيْ هِمْ أَمْوَٰلَ هُمْ وَ لَا تَأْكُلُ و هَآ إِسْرَافًا وَ بِدَارًا أَن يَكْبَرُ وا۟ وَ مَن كَانَ غَنِيًّا فَ لْ يَسْتَعْفِفْ وَ مَن كَانَ فَقِيرًا فَ لْ يَأْكُلْ بِ ٱلْ مَعْرُوفِ فَ إِذَا دَفَعْ تُمْ إِلَيْ هِمْ أَمْوَٰلَ هُمْ فَ أَشْهِدُ وا۟ عَلَيْ هِمْ وَ كَفَىٰ بِ ٱللَّهِ حَسِيبًا
And test the orphans [in their abilities] until they reach marriageable age. Then if you perceive in them sound judgement, release their property to them. And do not consume it excessively and quickly, [anticipating] that they will grow up. And whoever, [when acting as guardian], is self-sufficient should refrain [from taking a fee]; and whoever is poor - let him take according to what is acceptable. Then when you release their property to them, bring witnesses upon them. And sufficient is Allah as Accountant.
65:2
فَ إِذَا بَلَغْ نَ أَجَلَ هُنَّ فَ أَمْسِكُ و هُنَّ بِ مَعْرُوفٍ أَوْ فَارِقُ و هُنَّ بِ مَعْرُوفٍ وَ أَشْهِدُ وا۟ ذَوَىْ عَدْلٍ مِّن كُمْ وَ أَقِيمُ وا۟ ٱل شَّهَٰدَةَ لِ لَّهِ ذَٰلِكُمْ يُوعَظُ بِ هِۦ مَن كَانَ يُؤْمِنُ بِ ٱللَّهِ وَ ٱلْ يَوْمِ ٱلْ ءَاخِرِ وَ مَن يَتَّقِ ٱللَّهَ يَجْعَل لَّ هُۥ مَخْرَجًا
And when they have [nearly] fulfilled their term, either retain them according to acceptable terms or part with them according to acceptable terms. And bring to witness two just men from among you and establish the testimony for [the acceptance of] Allah. That is instructed to whoever should believe in Allah and the Last day. And whoever fears Allah - He will make for him a way out
7:172
وَ إِذْ أَخَذَ رَبُّ كَ مِنۢ بَنِىٓ ءَادَمَ مِن ظُهُورِ هِمْ ذُرِّيَّتَ هُمْ وَ أَشْهَدَ هُمْ عَلَىٰٓ أَنفُسِ هِمْ أَ لَسْ تُ بِ رَبِّ كُمْ قَالُ وا۟ بَلَىٰ شَهِدْ نَآ أَن تَقُولُ وا۟ يَوْمَ ٱلْ قِيَٰمَةِ إِنَّ ا كُ نَّا عَنْ هَٰذَا غَٰفِلِينَ
And [mention] when your Lord took from the children of Adam - from their loins - their descendants and made them testify of themselves, [saying to them], "Am I not your Lord?" They said, "Yes, we have testified." [This] - lest you should say on the day of Resurrection, "Indeed, we were of this unaware."
