وَمَا نُرْسِلُ ٱلْمُرْسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَ ۖ فَمَنْ ءَامَنَ وَأَصْلَحَ فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
We send not the messengers save as bearers of good news and warners. Whoso believeth and doeth right, there shall no fear come upon them neither shall they grieve.
Surah Al-An'aam(6:48)
