1. 2:178 يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُتِبَ عَلَيْكُمُ ٱلْقِصَاصُ فِى ٱلْقَتْلَى ٱلْحُرُّ بِٱلْحُرِّ وَٱلْعَبْدُ بِٱلْعَبْدِ وَٱلْأُنثَىٰ بِٱلْأُنثَىٰ فَمَنْ عُفِىَ لَهُۥ مِنْ أَخِيهِ شَىْءٌ فَٱتِّبَاعٌۢ بِٱلْمَعْرُوفِ وَأَدَآءٌ إِلَيْهِ بِإِحْسَٰنٍ ذَٰلِكَ تَخْفِيفٌ مِّن رَّبِّكُمْ وَرَحْمَةٌ فَمَنِ ٱعْتَدَىٰ بَعْدَ ذَٰلِكَ فَلَهُۥ عَذَابٌ أَلِيمٌ

   O you who believe! retaliation is prescribed for you in the matter of the slain, the free for the free, and the slave for the slave, and the female for the female, but if any remission is made to any one by his (aggrieved) brother, then prosecution (for the bloodwit) should be made according to usage, and payment should be made to him in a good manner; this is an alleviation from your Lord and a mercy; so whoever exceeds the limit after this he shall have a painful chastisement.
   

2. 2:283 وَإِن كُنتُمْ عَلَىٰ سَفَرٍ وَلَمْ تَجِدُوا۟ كَاتِبًا فَرِهَٰنٌ مَّقْبُوضَةٌ فَإِنْ أَمِنَ بَعْضُكُم بَعْضًا فَلْيُؤَدِّ ٱلَّذِى ٱؤْتُمِنَ أَمَٰنَتَهُۥ وَلْيَتَّقِ ٱللَّهَ رَبَّهُۥ وَلَا تَكْتُمُوا۟ ٱلشَّهَٰدَةَ وَمَن يَكْتُمْهَا فَإِنَّهُۥٓ ءَاثِمٌ قَلْبُهُۥ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ

   And if you are upon a journey and you do not find a scribe, then (there may be) a security taken into possession; but if one of you trusts another, then he who is trusted should deliver his trust, and let him be careful (of his duty to) Allah, his Lord; and do not conceal testimony, and whoever conceals it, his heart is surely sinful; and Allah knows what you do.
   

3. 3:75 وَمِنْ أَهْلِ ٱلْكِتَٰبِ مَنْ إِن تَأْمَنْهُ بِقِنطَارٍ يُؤَدِّهِۦٓ إِلَيْكَ وَمِنْهُم مَّنْ إِن تَأْمَنْهُ بِدِينَارٍ لَّا يُؤَدِّهِۦٓ إِلَيْكَ إِلَّا مَا دُمْتَ عَلَيْهِ قَآئِمًا ذَٰلِكَ بِأَنَّهُمْ قَالُوا۟ لَيْسَ عَلَيْنَا فِى ٱلْأُمِّيِّۦنَ سَبِيلٌ وَيَقُولُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ وَهُمْ يَعْلَمُونَ

   And among the followers of the Book there are some such that if you entrust one (of them) with a heap of wealth, he shall pay it back to you; and among them there are some such that if you entrust one (of them) with a dinar he shall not pay it back to you except so long as you remain firm in demanding it; this is because they say: There is not upon us in the matter of the unlearned people any way (to reproach); and they tell a lie against Allah while they know.
   

4. 4:58 إِنَّ ٱللَّهَ يَأْمُرُكُمْ أَن تُؤَدُّوا۟ ٱلْأَمَٰنَٰتِ إِلَىٰٓ أَهْلِهَا وَإِذَا حَكَمْتُم بَيْنَ ٱلنَّاسِ أَن تَحْكُمُوا۟ بِٱلْعَدْلِ إِنَّ ٱللَّهَ نِعِمَّا يَعِظُكُم بِهِۦٓ إِنَّ ٱللَّهَ كَانَ سَمِيعًۢا بَصِيرًا

   Surely Allah commands you to make over trusts to their owners and that when you judge between people you judge with justice; surely Allah admonishes you with what is excellent; surely Allah is Seeing, Hearing.
   

5. 44:18 أَنْ أَدُّوٓا۟ إِلَىَّ عِبَادَ ٱللَّهِ إِنِّى لَكُمْ رَسُولٌ أَمِينٌ

   Saying: Deliver to me the servants of Allah, surely I am a faithful messenger to you,
