The Prophet's Role as a Warner

وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ ءَايَةٌ مِّن رَّبِّهِۦٓ ۗ إِنَّمَآ أَنتَ مُنذِرٌ ۖ وَلِكُلِّ قَوْمٍ هَادٍ

And those who disbelieved say, "Why has a sign not been sent down to him from his Lord?" You are only a warner, and for every people is a guide.

عَلَىٰ قَلْبِكَ لِتَكُونَ مِنَ ٱلْمُنذِرِينَ

Upon your heart, [O Muḥammad] - that you may be of the warners -

۞ قُلْ إِنَّمَآ أَعِظُكُم بِوَٰحِدَةٍ ۖ أَن تَقُومُوا۟ لِلَّهِ مَثْنَىٰ وَفُرَٰدَىٰ ثُمَّ تَتَفَكَّرُوا۟ ۚ مَا بِصَاحِبِكُم مِّن جِنَّةٍ ۚ إِنْ هُوَ إِلَّا نَذِيرٌ لَّكُم بَيْنَ يَدَىْ عَذَابٍ شَدِيدٍ

Say, "I only advise you of one [thing] - that you stand for Allāh, [seeking truth] in pairs and individually, and then give thought." There is not in your companion any madness. He is only a warner to you before a severe punishment.

فَبَشِّرْهُم بِعَذَابٍ أَلِيمٍ

So give them tidings of a painful punishment,
