﴿ وَمَا نُرْسِلُ ٱلْمُرْسَلِينَ إِلَّا مُبَشِّرِينَ وَمُنذِرِينَ ۖ فَمَنْ ءَامَنَ وَأَصْلَحَ فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ ﴾

“And We send [Our] message-bearers only as heralds of glad tidings and as warners: hence, all who believe and live righteously -no fear need they have, and neither shall they grieve;”

We do not send messengers except as bearers of good tidings to those who believe good tidings of Paradise and as warners to those who disbelieve warning of the Fire. Whoever believes in them and makes amends in his deeds no fear shall befall them neither shall they grieve in the Hereafter.
