Surat Al-A'raaf (The Heights) - الأعراف

قَالَ ٱلْمَلَأُ ٱلَّذِينَ كَفَرُوا۟ مِن قَوْمِهِۦٓ إِنَّا لَنَرَىٰكَ فِى سَفَاهَةٍ وَإِنَّا لَنَظُنُّكَ مِنَ ٱلْكَٰذِبِينَ ﴿٦٦﴾ قَالَ يَٰقَوْمِ لَيْسَ بِى سَفَاهَةٌ وَلَٰكِنِّى رَسُولٌ مِّن رَّبِّ ٱلْعَٰلَمِينَ﴿٦٧﴾

The chiefs of those who disbelieved from among his people said: Most surely we see you in folly, and most surely we think you to be of the liars. He said: O my people! there is no folly in me, but I am an apostle of the Lord of the worlds.
