Ar-Rum - 30:47

وَلَقَدْ أَرْسَلْنَا مِن قَبْلِكَ رُسُلًا إِلَى قَوْمِهِمْ فَجَاؤُوهُم بِالْبَيِّنَاتِ فَانتَقَمْنَا مِنَ الَّذِينَ أَجْرَمُوا وَكَانَ حَقًّا عَلَيْنَا نَصْرُ الْمُؤْمِنِينَ
[30:47]
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.
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.
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.
