أَوَلَمْ يَتَفَكَّرُوا۟ ۗ مَا بِصَاحِبِهِم مِّن جِنَّةٍ ۚ إِنْ هُوَ إِلَّا نَذِيرٌ مُّبِينٌ

Then do they not give thought? There is in their companion [i.e., Muḥammad (ﷺ)] no madness. He is not but a clear warner.

Al-A'raf 184

قَالَ ٱلْمَلَأُ ٱلَّذِينَ ٱسْتَكْبَرُوا۟ مِن قَوْمِهِۦ لِلَّذِينَ ٱسْتُضْعِفُوا۟ لِمَنْ ءَامَنَ مِنْهُمْ أَتَعْلَمُونَ أَنَّ صَـٰلِحًا مُّرْسَلٌ مِّن رَّبِّهِۦ ۚ قَالُوٓا۟ إِنَّا بِمَآ أُرْسِلَ بِهِۦ مُؤْمِنُونَ

Said the eminent ones who were arrogant among his people to those who were oppressed - to those who believed among them, "Do you [actually] know that Ṣāliḥ is sent from his Lord?" They said, "Indeed we, in that with which he was sent, are believers."

Al-A'raf 75

وَلَقَدْ أَرْسَلْنَا نُوحًا إِلَىٰ قَوْمِهِۦٓ إِنِّى لَكُمْ نَذِيرٌ مُّبِينٌ

And We had certainly sent Noah to his people, [saying], "Indeed, I am to you a clear warner

Hud 25

أَلَّا تَعْبُدُوٓا۟ إِلَّا ٱللَّهَ ۚ إِنَّنِى لَكُم مِّنْهُ نَذِيرٌ وَبَشِيرٌ

[Through a messenger, saying], "Do not worship except Allāh. Indeed, I am to you from Him a warner and a bringer of good tidings,"

Hud 2

وَمَآ أَرْسَلْنَا مِن قَبْلِكَ إِلَّا رِجَالًا نُّوحِىٓ إِلَيْهِمْ ۚ فَسْـَٔلُوٓا۟ أَهْلَ ٱلذِّكْرِ إِن كُنتُمْ لَا تَعْلَمُونَ

And We sent not before you except men to whom We revealed [Our message]. So ask the people of the message [i.e., former scriptures] if you do not know.
