Sura 4 An-Nisa (The Women), aja 86

1. وَإِذَا حُيِّيتُمْ بِتَحِيَّةٍ فَحَيُّوا بِأَحْسَنَ مِنْهَا أَوْ رُدُّوهَا ۗ إِنَّ اللَّهَ كَانَ عَلَىٰ كُلِّ شَيْءٍ حَسِيبًا

   And when you are greeted with a greeting, greet (in return) with one better than it or (at least) return it (in a like manner). Indeed, Allah is ever, over all things, an Accountant.

   4:86
