Surah Al-Anfal (The Spoils of War), Verse 33

وَمَا كَانَ اللّٰهُ لِیُعَذِّبَهُمْ وَاَنْتَ فِیْهِمْ وَمَا كَانَ اللّٰهُ مُعَذِّبَهُمْ وَهُمْ یَسْتَغْفِرُوْنَ ۟

Wa maa kaanal laahu liyu'az zibahum wa anta feehim; wa maa kaanal laahu mu'az zibahum wa hum yastaghfiroon

“But Allah was not going to send them a penalty whilst thou wast amongst them; nor was He going to send it whilst they could ask for pardon.”
