Qur'an 5:67

۞ يَـٰٓأَيُّهَا ٱلرَّسُولُ بَلِّغْ مَآ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ ۖ وَإِن لَّمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُۥ ۚ وَٱللَّهُ يَعْصِمُكَ مِنَ ٱلنَّاسِ ۗ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَـٰفِرِينَ

O Messenger! Make known that which hath been revealed unto thee from thy Lord, for if thou do it not, thou wilt not have conveyed His message. Allah will protect thee from mankind. Lo! Allah guideth not the disbelieving folk.
