4: 86 [an-Nisa, Medina 92 ]

Asad But when you are greeted with a greeting [of peace], answear with an even better greeting, or [at least] with the like thereof. Verily, God keeps count indeed of all things.

Yusuf Ali When a (courteous) greeting is offered you meet it with a greeting still more courteous (at least) of equal courtesy. Allah takes careful account of all things.

Pickthall When ye are greeted with a greeting, greet ye with a better than it or return it. Lo! Allah taketh count of all things.

Wa iza_ huyyitum bi tahiyyatin fa hayyu_ bi ahsana minha_ au ruddu_ha_, innalla_ha 'ala_ kulli syai'in hasiba_(n).

[[ Ruby’s note – This is revealed in the context of war and God commanding fighting resolutely in a war, etc. Then God is mentioning about the greeting which may seem trivial or mundane thing compare to war, but for a life to be successful big and small all things count and God notes all the details. Even greeting may seem a mall matter, this is one of the most repeated events in life. Greeting is also important from social aspect: it helps to have a courteous and better relationship among the people one lives with and make others feel welcome and at home. These small acts often go a long way in helping contribute towards bigger events and achievements including making one a better, caring and courteous member of a family and a society.]]
