Avoiding the Haram whilst engaging in transactions

وَلَا تَقْرَبُوا۟ مَالَ ٱلْيَتِيمِ إِلَّا بِٱلَّتِى هِىَ أَحْسَنُ حَتَّىٰ يَبْلُغَ أَشُدَّهُۥ ۖ وَأَوْفُوا۟ ٱلْكَيْلَ وَٱلْمِيزَانَ بِٱلْقِسْطِ ۖ لَا نُكَلِّفُ نَفْسًا إِلَّا وُسْعَهَا ۖ وَإِذَا قُلْتُمْ فَٱعْدِلُوا۟ وَلَوْ كَانَ ذَا قُرْبَىٰ ۖ وَبِعَهْدِ ٱللَّهِ أَوْفُوا۟ ۚ ذَٰلِكُمْ وَصَّىٰكُم بِهِۦ لَعَلَّكُمْ تَذَكَّرُونَ

And come not nigh to the orphan's property, except to improve it, until he attain the age of full strength; give measure and weight with (full) justice;- no burden do We place on any soul, but that which it can bear;- whenever ye speak, speak justly, even if a near relative is concerned; and fulfil the covenant of Allah: thus doth He command you, that ye may remember.

۞ أَوْفُوا۟ ٱلْكَيْلَ وَلَا تَكُونُوا۟ مِنَ ٱلْمُخْسِرِينَ

"Give just measure, and cause no loss (to others by fraud).

وَزِنُوا۟ بِٱلْقِسْطَاسِ ٱلْمُسْتَقِيمِ

"And weigh with scales true and upright.

وَلَا تَبْخَسُوا۟ ٱلنَّاسَ أَشْيَآءَهُمْ وَلَا تَعْثَوْا۟ فِى ٱلْأَرْضِ مُفْسِدِينَ

"And withhold not things justly due to men, nor do evil in the land, working mischief.

أَلَّا تَطْغَوْا۟ فِى ٱلْمِيزَانِ

In order that ye may not transgress (due) balance.

وَأَقِيمُوا۟ ٱلْوَزْنَ بِٱلْقِسْطِ وَلَا تُخْسِرُوا۟ ٱلْمِيزَانَ

So establish weight with justice and fall not short in the balance.
