Surah Al-An'am (The Cattle), Verse 48

وَمَا نُرْسِلُ الْمُرْسَلِیْنَ اِلَّا مُبَشِّرِیْنَ وَمُنْذِرِیْنَ فَمَنْ اٰمَنَ وَاَصْلَحَ فَلَا خَوْفٌ عَلَیْهِمْ وَلَا هُمْ یَحْزَنُوْنَ ۟

Wa maa nursilul mursaleena illaa mubashshireena wa munzireena faman aamana wa aslaha falaa khawfun 'alaihim wa laa hum yahzanoon

“We send the messengers only to give good news and to warn: so those who believe and mend (their lives),- upon them shall be no fear, nor shall they grieve.”
