Quran 6:48 from Surah Al-An'aam on Divine Marvels.
وَمَا نُرۡسِلُ ٱلۡمُرۡسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَۖ فَمَنۡ ءَامَنَ وَأَصۡلَحَ فَلَا خَوۡفٌ عَلَيۡهِمۡ وَلَا هُمۡ يَحۡزَنُونَ
English translation: And not We send the Messengers except (as) bearer of glad tidings and (as) warners So whoever believed and reformed then no fear upon them and not they will grieve
Transliteration: wama nur'silu al-mur'salina illa mubashirina wamundhirina faman amana wa-aslaha fala khawfun alayhim wala hum yahzanuna
