1. 4:6An-Nisa
   وَٱبۡتَلُواْ ٱلۡيَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُواْ ٱلنِّكَاحَ فَإِنۡ ءَانَسۡتُم مِّنۡهُمۡ رُشۡدٗا فَٱدۡفَعُوٓاْ إِلَيۡهِمۡ أَمۡوَٰلَهُمۡۖ وَلَا تَأۡكُلُوهَآ إِسۡرَافٗا وَبِدَارًا أَن يَكۡبَرُواْۚ وَمَن كَانَ غَنِيّٗا فَلۡيَسۡتَعۡفِفۡۖ وَمَن كَانَ فَقِيرٗا فَلۡيَأۡكُلۡ بِٱلۡمَعۡرُوفِۚ فَإِذَا دَفَعۡتُمۡ إِلَيۡهِمۡ أَمۡوَٰلَهُمۡ فَأَشۡهِدُواْ عَلَيۡهِمۡۚ وَكَفَىٰ بِٱللَّهِ حَسِيبٗا
   Prove orphans till they reach the marriageable age; then, if ye find them of sound judgment, deliver over unto them their fortune; and devour it not by squandering and in haste lest they should grow up Whoso (of the guardians) is rich, let him abstain generously (from taking of the property of orphans); and whoso is poor let him take thereof in reason (for his guardianship). And when ye deliver up their fortune unto orphans, have (the transaction) witnessed in their presence. Allah sufficeth as a Reckoner.
   In context

   Guardians, test the orphans when they are near to reaching maturity, by giving them a part of their wealth to see how they manage it. If they manage it well, and show you their sound judgement, hand over their property in full. Do not use up their wealth, overstepping the limits which Allah has approved for you: use their wealth only when necessary.

2. 4:86An-Nisa
   وَإِذَا حُيِّيتُم بِتَحِيَّةٖ فَحَيُّواْ بِأَحۡسَنَ مِنۡهَآ أَوۡ رُدُّوهَآۗ إِنَّ ٱللَّهَ كَانَ عَلَىٰ كُلِّ شَيۡءٍ حَسِيبًا
   When ye are greeted with a greeting, greet ye with a better than it or return it. Lo! Allah taketh count of all things.

   When anyone offers a greeting of peace to you, then respond to him with something better than what he offered or return a similar greeting to him. To respond with something better is more virtuous. Allah keeps watch over what you do and He will reward each person according to his actions.

   (And it will be said unto him): Read thy Book. Thy soul sufficeth as reckoner against thee this day.
