And We have already sent messengers before you to their peoples, and they came to them with clear evidences; then We took retribution from those who committed crimes, and incumbent upon Us was support of the believers.

And indeed We did send Messengers before you (O Muhammad SAW) to their own peoples. They came to them with clear proofs, then, We took vengeance on those who committed crimes (disbelief, setting partners in worship with Allah, sins, etc.), and (as for) the believers it was incumbent upon Us to help (them).

Verily We sent before thee (Muhammad) messengers to their own folk. Then we took vengeance upon those who were guilty (in regard to them). To help believers is ever incumbent upon Us.

We did indeed send, before thee, messengers to their (respective) peoples, and they came to them with Clear Signs: then, to those who transgressed, We meted out Retribution: and it was due from Us to aid those who believed.
Shakir
And certainly We sent before you messengers to their people, so they came to them with clear arguments, then We gave the punishment to those who were guilty; and helping the believers is ever incumbent on Us.

And indeed We sent even before you Messengers to their people; then they came to them with the supreme evidence. So We took vengeance upon (those) who (committed) crimes; and it is truly (binding) on Us to (give) victory to the believers.
