When you are greeted with a greeting, greet in return with what is better than it, or (at least) return it equally. Certainly, Allah is Ever a Careful Account Taker of all things.
Na mnapo amkiwa kwa maamkio yoyote, basi nanyi itikieni kwa yaliyo bora kuliko hayo, au rejesheni hayo hayo. Hakika Mwenyezi Mungu ni Mwenye kuhisabu kila kitu.
