Ya-Sin
قَالُوا۟ مَآ أَنتُمْ إِلَّا بَشَرٌ مِّثْلُنَا وَمَآ أَنزَلَ ٱلرَّحْمَـٰنُ مِن شَىْءٍ إِنْ أَنتُمْ إِلَّا تَكْذِبُونَ
They said, "You are not but human beings like us, and the Most Merciful has not revealed a thing. You are only telling lies."

وَٱضْرِبْ لَهُم مَّثَلًا أَصْحَـٰبَ ٱلْقَرْيَةِ إِذْ جَآءَهَا ٱلْمُرْسَلُونَ
And present to them an example: the people of the city, when the messengers came to it -
إِذْ أَرْسَلْنَآ إِلَيْهِمُ ٱثْنَيْنِ فَكَذَّبُوهُمَا فَعَزَّزْنَا بِثَالِثٍ فَقَالُوٓا۟ إِنَّآ إِلَيْكُم مُّرْسَلُونَ
When We sent to them two but they denied them, so We strengthened them with a third, and they said, "Indeed, we are messengers to you."
قَالُوا۟ رَبُّنَا يَعْلَمُ إِنَّآ إِلَيْكُمْ لَمُرْسَلُونَ
They said, "Our Lord knows that we are messengers to you,
وَمَا عَلَيْنَآ إِلَّا ٱلْبَلَـٰغُ ٱلْمُبِينُ
And we are not responsible except for clear notification."
